Brian Behlendorf 8e43fa12c5 Fix vdev_rebuild_thread deadlock
The metaslab_disable() call may block waiting for a txg sync.
Therefore it's important that vdev_rebuild_thread release the
SCL_CONFIG read lock it is holding before this call.  Failure
to do so can result in the txg_sync thread getting blocked
waiting for this lock which results in a deadlock.
