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.
