[PATCH] signal: remove unused variable mask

[Colin King]

From: Colin Ian King <colin.k...@canonical.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()")
