IOW, we could move it under "if (!uprobe)" branch, but we do not.

This is mostly needed for 2/5, which in turn is needed for 3/5.
If can_skip_sstep() succeeds we need to reset utask->state too.

ALternatively we could start with 4/5, but this is the "separate"
change (and it is not bug-fix) which needs your review/ack.

Oleg.
