[v2,0/2] nfsd: ensure we wake file lock waiters before deleting blocked lock

This is a respin of the patch that I sent over the weekend. It's a bit
more obvious to just call locks_delete_block from free_blocked_lock,
and that allows us to remove that call from some other sites.

Still though, I think we probably do want to wake blocked lock requests
prior to sending a callback to ensure that they can make progress when
the callback isn't getting a reply. The second patch does this.
