qcacld-3.0: Populate correct dot11_mode during CSA

Browse source 
When CSA is received from the firmware, dot11_mode is copied
from received message . In response to the CSA message, the host
invokes wma_vdev_start with isRestart flag set to restart the
vdev with the new updated channel, and channel params.
The dot11_mode value is copied from the CSA which will not be a
problem unless the switching channel is on the same band or on
different band as long as its HT/VHT 2.4GHZ to HT/VHT 5GHZ bands
or vice-versa. When the channel switch occurs from a 11a to 11g
band or vice-versa, wrong dot11_mode is populated without being
updated for the new band. As the phy_mode is calculated from the
dot11_mode value, phy_mode check fails in wma_vdev_start in this
case. So the host doesn't send vdev_restart.

Populate the dot11_mode correctly and pass it to lower layers
upon updation. This will ensure correct phy_mode is calculated
and vdev_restart is sent.
