ceph: fix ceph_lookup_open intent usage
We weren't properly calling lookup_instantiate_filp when setting up the lookup intent, which could lead to file leakage on errors. So: - use separate helper for the hidden snapdir translation, immediately following the mds request - use ceph_finish_lookup for the final dentry/return value dance in the exit path - lookup_instantiate_filp on success Reported-by: Al Viro <viro@ZenIV.linux.org.uk> Reviewed-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
