This patch ensures uniformity in event skb sent by interface code
(USB/PCIe/SDIO) which automatically fixes following bugs.

1) For USB interface, same buffer is reused for receiving cmd and
events from firmware. While handling events, we perform
skb_pull(skb, 4) to remove event header. Corresponding skb_push()
call is missing while submitting the buffer.
2) For PCIe interface, event skb is passed with event header.
Recently added uAP events EVENT_UAP_STA_ASSOC, EVENT_UAP_STA_DEAUTH
will not work for PCIe, as they assume event skb points to event body.

Adding casts of objects to the same type is unnecessary
and confusing for a human reader.

For example, this cast:

        int y;
        int *p = (int *)&y;

I used the coccinelle script below to find and remove these
unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

@@
type T;
T *p;

-       (T *)p
+       p

Added logic to handle AP event that are generated
by the firmware. As MLME/SME is implemented in the
firmware, events such as station association and
deauthentication, must be sent to userspace (hostapd)
for creating and deleting station database.

In this handler LOW_RSSI and HIGH_RSSI events are subscribed
to FW using provided threshold value so that FW will monitor
connection quality and trigger any of these events.

Driver will notify cfg80211 about connection quality based on
inputs from FW and provided hysteresis.

2) As noise and signal vaules in private structure already get

cfg_workqueue was added to notify cfg80211 that scan, connect
or disconnect is done by calling respective completion handlers.
We can avoid use of this workqueue by calling those handlers
from other places.
1) Call connect, disconnect completion handlers in their callback
   functions.
   ex. Call cfg80211_connect_result() in mwifiex_cfg80211_connect()
2) Call scan completion handler after parsing response of last scan
   command in a queue.

After removing the workqueue, variables (assoc_request etc.) and
checks used for mutual exclusion become redundant. Those are also
removed in this patch.

Instead of maintaining static scan table in driver, scan list is sent
to cfg80211 stack (after parsing each scan command response).
In assoc handler (for infra and ibss network) requested BSS information
is retrieved using cfg80211_get_bss() API.

With the changes above some redundant code are removed.
