Subject: [PATCH] signal: remove unused variable mask

From: Colin Ian King <colin.king@...onical.com>

The variable mask was introduced by an earlier commit and does not seem
to be used, so remove it.

Fixes gcc warning:
kernel/signal.c:3443:19: warning: unused variable ‘mask’ [-Wunused-variable]

Fixes: fc271087ebcb ("signal: replace sigset_to_compat() with put_compat_sigset()")
