David Howells fe9453a1dc KEYS: Revert one application of "Fix unreachable code" patch 
A patch to fix some unreachable code in search_my_process_keyrings() got
applied twice by two different routes upstream as commits e67eab39be
and b010520ab3 (both "fix unreachable code").

Unfortunately, the second application removed something it shouldn't
have and this wasn't detected by GIT.  This is due to the patch not
having sufficient lines of context to distinguish the two places of
application.

The effect of this is relatively minor: inside the kernel, the keyring
search routines may search multiple keyrings and then prioritise the
errors if no keys or negative keys are found in any of them.  With the
extra deletion, the presence of a negative key in the thread keyring
(causing ENOKEY) is incorrectly overridden by an error searching the
process keyring.

So revert the second application of the patch.
