description:
Refactor condition for iwm_init.

We only have to check to see if the device has stopped before calling
iwm_init.

The device has been put into the stopped state on attach more importantly
the device is marked IWM_FLAG_STOPPED.  The device is already in a stopped
state when leaving attach from code in iwm_preinit, but it is not marked
IWM_STOPPED.

This change ensures the device is marked stopped and be inited after
suspend/resume or a cold boot.
