[PATCH] Keys: Get rid of warning in kmod.c if keys disabled

[David Howells <dhowells@redhat.com>]

The attached patch gets rid of a "statement without effect" warning when
CONFIG_KEYS is disabled by making use of the return value of key_get(). The
compiler will optimise all of this away when keys are disabled.
