wlan: Address kernel panic due to asynchronous access of ROC context
Due to the race between supplicant thread and McThread where the
remain_on_chan context is made NULL and the __wlan_hdd_mgmt_tx
function in supplicant thread context tries to access the released
roc context results in kernel panic.
To mitigate this issue extend mutex lock to wlan_hdd_mgmt_tx function
to avoid asynchronous access to the remain_on_chan_ctx.
