FROMLIST: Revert "lockd: Show pid of lockd for remote locks"

This reverts most of commit b8eee0e90f97 ("lockd: Show pid of lockd for
remote locks"), which caused remote locks to not be differentiated between
remote processes for NLM.

We retain the fixup for setting the client's fl_pid to a negative value.
