[REVIEW][PATCH 12/26] signal/um: Remove task parameter from send_sigtrap

["Eric W. Biederman" <ebiederm@xmission.com>]

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.
