Looks that we do not set correctly antennas when scanning
on 5Ghz band and when bluetooth is enabled, because
priv->cfg->scan_tx_antennas[band] is only defined for
IEEE80211_BAND_2GHZ.

To fix we check band before limiting antennas to first one.
This allow to remove hard coded cfg->scan_tx_antennas[band].

The initialization function used by hci_open_dev (hci_init_req) sends
many different HCI commands. The __hci_request function should only
return when all of these commands have completed (or a timeout occurs).
Several of these commands cause hci_req_complete to be called which
causes __hci_request to return prematurely.

This patch fixes the issue by adding a new hdev->req_last_cmd variable
which is set during the initialization procedure. The hci_req_complete
function will no longer mark the request as complete until the command
matching hdev->req_last_cmd completes.

It looks like some hardware registers are left into undefined state
after suspend/resume. At minimum, this can cause odd issues related to
key cache and hardware trying to encrypt/decrypt frames unexpectedly.
This seems to happen even when there is no keys configured, i.e., hardware
can end up touching TX frames just based of invalid key cache context
even if the driver is not asking a specific entry to be used. In
addition, RX can likely be affected. This patch fixes this issue.

Sometimes device returns wrong number of items in bssid-list. Appears that
some specific beacons trigger this problem and leads to very poor scanning
results. Workaround by ignoring num_items received from device and walkthrough
full bssid-list buffer.

v2: Fix buffer range checks and reading next item length. Old code read
    behind buffer on last item but didn't use those values as 'count' would
    also reach zero. Also fix resizing of buffer if device has larger buffer,
    old code assumed that BSSID-list OID would return same buffer size
    when it really can return yet another new larger length.

Add a new variable to keep track of the currently configured tx power. Before
max_pwr was re-used for keeping the maximum allowed power as well as the
current configuration. Doing a min() on it allows you to lower the txpower, but
how would you be able to make it higher again?

This patch fixes that by adding a new variable ah_cur_pwr which is used instead
of txp_max_pwr to keep the current configuration. txp_max_pwr is used to check
if we are within the limits.

Another problem fixed by this patch is that it avoids setting a zero txpower
when things are initialized first and the current power is not yet set.
