1) Recently we removed set_channel cfg80211 handler. Also, cfg80211
blocks ibss connection requests if ibss network is already started
/joined. Hence the code to restart ibss network in new channel
(mwifiex_drv_change_adhoc_chan() function) becomes redundant.

2) mwifiex_bss_set_channel() function is redundant. It does some
error checking and calculate adhoc start band and adhoc channel.
Cfg80211 already takes care of error checking and provides correct
channel information to the driver. Adhoc start band is already
calculated in mwifiex_set_rf_channel() function.

Other associated code is also removed in this patch.

We get two timing related fields for each bss from firmware in scan
results.
1) timestamp - Actual timestamp information in probe response/beacon
2) network_tsf - firmware's TSF value at the time the beacon or probe
response was received.
Both are needed while associating by firmware.

The patch takes care of following things.
1) We should pass "timestamp" to cfg80211_inform_bss(), but currently
"network_tsf" is being provided. This error is corrected here.
2) Rename "network_tsf" to "fw_tsf"
3) Make use of u64 variable instead of an array of u8/u32 to save
parsed "timestamp" information.
4) Use timestamp provided to stack in scan results using
cfg80211_inform_bss() while associating. (bss->tsf)
5) Allocate space to save fw_tsf in "priv" of cfg80211_bss
and retrieve it while associating.

IEEE80211_MAX_QUEUES is an internal mac80211 value,
it is not guaranteed to be always 4. The firmware
API in mwifiex almost certainly doesn't care about
mac80211 changing though, so mwifiex shouldn't use
this value.

Maybe it should use IEEE80211_NUM_ACS instead and
that is what I'm doing here as at least that value
will probably never change, but maybe it should
have its own define instead.

Currently if valid SSID list is provided in scan request, driver
performs specific SSID scan otherwise wildcard scan is chosen.

When wpa_supplicant provides valid SSID list followed by
zero-length SSID for wildcard scan, only specific SSID scan is
performed by driver. Actually driver is expected to do both type
of scanning in this case. The patch fixes this issue.
