signal: Remove task parameter from force_sigsegv
The function force_sigsegv is always called on the current task so passing in current is redundant and not passing in current makes this fact obvious. This also makes it clear force_sigsegv always calls force_sig on the current task. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
