Amitkumar Karwar d2b0c735eb mwifiex: handle start AP error paths correctly 
It's been observed that even if firmware returns an error
for a configuration command, we go ahead and start AP.

This patch changes the command type from async to sync
so that threads waits for command response and return
failure start AP.
