do_sigaction: don't worry about signal_pending()

do_sigaction() returns -ERESTARTNOINTR if signal_pending(). The comment says:

	* If there might be a fatal signal pending on multiple
	* threads, make sure we take it before changing the action.

I think this is not needed. We should only worry about SIGNAL_GROUP_EXIT case,
bit it implies a pending SIGKILL which can't be cleared by do_sigaction.

Kill this special case.
