input: fix uninitialized old_keycode oops in input_set_keycode

Patch as suggested by Kyle McMartin, in response to Red Hat bugzilla 615707, filed against a rawhide kernel carrying ir-core enabling patches from the linuxtv staging/other tree. Fix is based on the similar logic in input_set_keycode_big, and is confirmed by the bz reporter.
