wlan: Fix race condition for reliable delivery of action frames.

There is race between McThread and Linux netlink thread.
Expiration of remain on channel in driver and also extending
remain on channel to send an action frame are happening
at the same time. After extending remain on channel in HDD,
remain on channel context becomes NULL at a later point when
driver is about to call SME API to send action frame and
this fix will help to start a fresh remain on channel as the
remain on channel context was NULL.
