ceph: invalidate affected dentry leases on aborted requests
If we abort a request, we return to caller, but the request may still complete. And if we hold the dir FILE_EXCL bit, we may not release a lease when sending a request. A simple un-tar, control-c, un-tar again will reproduce the bug (manifested as a 'Cannot open: File exists'). Ensure we invalidate affected dentry leases (as well dir I_COMPLETE) so we don't have valid (but incorrect) leases. Do the same, consistently, at other sites where I_COMPLETE is similarly cleared.
