Fix overly broad locking in spa_vdev_config_exit() 
Calling vdev_free() only requires the we acquire the spa config
SCL_STATE_ALL locks, not the SCL_ALL locks.  In particular, we need
need to avoid taking the SCL_CONFIG lock (included in SCL_ALL) as a
writer since this can lead to a deadlock.  The txg_sync_thread() may
block in spa_txg_history_init_io() when taking the SCL_CONFIG lock
as a reading when it detects there's a pending writer.
