gfapi: set lkowner in glfd

We need a provision to be able to set lkowner (which is
used to distinguish locks maintained by server) in gfapi.
Since the same lk_owner need to be used to be able to
flush the lock while closing the fd, store the lkowner
in the glfd structure itself.

A new API has been added to be able to set lkowner in glfd.

This is backport of below mainline fix -
