    iwn - Fix global serializer usage for iwn_init().
    
    Iwn_init_locked() calls iwn_read_firmware() which must drop the serializer
    since reading the firmware can block in a taskq.  Iwn_init_locked() is
    called by several entry points which must be serialized thus ensure that
    iwn_init_locked() is always called with the serializer held.
