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