signal/sh: Remove tsk parameter from force_sig_info_fault

The force_sig_info_fault function is always called with tsk == current. Make that explicit by removing the tsk parameter. This also makes it clear that the sh force_sig_info_fault passes current into force_sig_fault. Signed-off-by: "Eric W. Biederman" <[email protected]>
