[PATCH] NET: sunrpc, remove unneeded NULL tests

[Jiri Slaby <jslaby@suse.cz>]

Stanse found that req in xprt_reserve_xprt is dereferenced prior its
test to NULL. If that's the case, the checks are unnecessary, so
remove them.

The alternative is not to dereference it before the test. The patch
is to point out the problem, you have to decide.
