Ben's patch is a no-brainer but it is not yet in mainline or linux-next.
I'm not on linux-nfs so I recreated it as below.
Subject: sunrpc: propagate errors from xs_bind() through xs_create_sock()
From: Ben Hutchings <bhutchings@solarflare.com>
xs_create_sock() is supposed to return a pointer or an ERR_PTR-encoded
error, but it currently returns 0 if xs_bind() fails. This causes the
kernel to go BUG, as described in
https://bugzilla.kernel.org/show_bug.cgi?id=30322.

It is in linux-next. I've queued it up as part of a bugfix dump to Linus
this weekend.
