wifi: Ensure supplicant stopped in wifi_stop_supplicant

Commit 3674b8ab31a628c5d0834890ba3549bf8badf4ea introduces the
wifi_fst module, with a coding mistake, wifi_stop_supplicant
will return even supplicant is not really stopped.
If wifi_start_supplicant is called immediately, race condition
will happen in init process, which makes supplicant not start.

This change is to ensure supplicant really stopped before
wifi_stop_supplicant return.
