With the addition of the try_break_lease calls in directory changing
operations, allow generic_setlease to hand them out.
Note that this also makes directory leases available to userland via
fcntl(). I don't see a real reason to prevent userland from acquiring
one, but we could reinstate the prohibition if that's preferable.
