Brian Behlendorf 37c56346cc Close possible zfs_znode_held() race
Check if the lock is held while holding the z_hold_locks() lock.
This prevents a possible use-after-free bug for callers which are
not holding the lock.  There currently are no such callers so this
can't cause a problem today but it has been fixed regardless.
