Subject: [PATCH] sunrpc: removed redundant procp check

since vs_proc pointer is dereferenced before getting it's address there's
no need to check for NULL.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 8e5b67731d08 ("SUNRPC: Add a callback to initialise server requests")
