PATCH "mwifiex: scan delay timer cleanup in unload path" adds code
to cancel scan delay timer in unload path. It causes a regression
for USB interface.

USB8797 card gets enumerated twice. First enumeration is for
firmware download and second enumeration expects firmware
initialization.

It was observed that we are trying del_timer_sync() without setting
up the timer when remove handler is called after first enumeration.

This patch moves setup_timer() call to appropriate place so that
timer is setup for both the enumerations.
