wlan: Send the correct supported channel width in Assoc Resp.

Currently, if SAP supports 40Mhz, then it sends the supported
channel width as 40Mhz irrespective whether STA supports or not.

Changes done to check the STA capability for supported channel
width and send it accordingly in Assoc Resp.

wlan: Deregistering STA with correct STA ID.

In IBSS, whenever we recieve eCSR_ROAM_IBSS_LEAVE
indication, we assign sta id as 0 which is for MC/BC
packets and pass it to hdd_roamDeregisterSTA. Thus,
only sta id 0 gets deregistered while sta id for
UC frames remains as it is.

This fix will deregister station both for UC frames
as well as BC/MC frames.
