features/locks: error-out {inode,entry}lk fops with all-zero lk-owner

Problem:
Sometimes we find that developers forget to assign lk-owner for an
inodelk/entrylk/lk before writing code to wind these fops. locks
xlator at the moment allows this operation. This leads to multiple
threads in the same client being able to get locks on the inode
because lk-owner is same and transport is same. So isolation
with locks can't be achieved.

Fix:
Disallow locks with lk-owner zero.
