signal/nds32: Remove tsk parameter from send_sigtrap
The send_sigtrap function is always called with tsk == current. Make that obvious by removing the tsk parameter. This also makes it clear that send_sigtrap always calls force_sig_fault on the current task. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
