lockd: Remove FL_LOCKD flag
Currently lockd identifies its own locks using the FL_LOCKD flag. This
doesn't scale well to multiple lock managers--if we did this in nfsv4 too,
for example, we'd be left with only one free flag bit.
Instead, we just check whether the file manager ops (fl_lmops) set on this
lock are our own.
The only use for this is in nlm_traverse_locks, which uses it to find locks
that need cleaning up when freeing a host or a file.
In the long run it might be nice to do reference counting instead of
traversing all the locks like this....
