ceph: fix open file counting on snapped inodes when mds returns no caps
It's possible the MDS will not issue caps on a snapped inode, in which case an open request may not __ceph_get_fmode(), botching the open file counting. (This is actually a server bug, but the client shouldn't BUG out in this case.) Signed-off-by: Sage Weil <sage@newdream.net>
