select: shift restore_saved_sigmask_unless() into poll_select_copy_remaining()
Now that restore_saved_sigmask_unless() is always called with the same
argument right before poll_select_copy_remaining() we can move it into
poll_select_copy_remaining() and make it the only caller of restore() in
fs/select.c.
The patch also renames poll_select_copy_remaining(),
poll_select_finish() looks better after this change.
kern_select() doesn't use set_user_sigmask(), so in this case
poll_select_finish() does restore_saved_sigmask_unless() "for no
reason". But this won't hurt, and WARN_ON(!TIF_SIGPENDING) is still
valid.
