leases:Mark the fop conflicting if lease_id not set

Glusterfs leases expects lease_id to be set and sent
for each fop to determine conflict resolution with the
existing lease.
Incase if not set (most likely if there is an older
client in a mixed cluster), it makes sense to consider
it as conflicitng fop and recall the lease.

Also fixed the return status check for __remove_lease(),
wherein non-negative value is considered as success case.
