Fix zpool on zvol deadlock
Commit 65d56083b4617a4cade0cff68cbbaf68114169d6 fixes the lock
inversion between spa_namespace_lock and bdev->bd_mutex but only
for the first user of spa_namespace_lock: dmu_objset_own().
Later spa_namespace_lock gets acquired by dsl_prop_get_integer()
though dsl_prop_get()->dsl_dataset_hold()->dsl_dir_open_spa()->
spa_open()->spa_open_common() without this "protection". By
moving the mutex release after this second use, even this
acquisition of the lock is "protected" by the ERESTARTSYS trick.
