smartpqi: Drop spinlock before freeing memory

Browse source 
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.
