    smartpqi: Drop spinlock before freeing memory
    
    pqisrc_free_device frees the device softc with the os spinlock
    held. This causes crashes when devices are removed because the memory
    free might sleep (which is prohibited with spin locks held). Drop the
    spinlock before releasing the memory.
