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.
