Merge branch 'bug-fixes-for-net-handshake'

Chuck Lever says:

====================
Bug fixes for net/handshake

Paolo observed that there is a possible leak of sock->file. I
haven't looked into that yet, but it seems to be separate from
the fixes in this series, so no need to hold these up.
====================

The submissions mentions net-next but it means netdev (perhaps
merge window left over when trees are converged). In any case,
it should have gone into net, but was instead applied to net-next
as commit deb2e484baf9 ("Merge branch 'net-handshake-fixes'").
These are fixes tho, and Chuck needs them to make progress with
the client so double-merging them into net... it is what it is :(
