mwifiex: handle start AP error paths correctly

BugLink: https://launchpad.net/bugs/1528910

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.
