worker: check problem state correctly (issue3982)

If a large update triggered an abort, it was possible for the main
thread to still update the dirstate.

This fix is incomplete, as the failing worker now doesn't generate a
proper error message. This is difficult in the fork-based framework,
which relies on exceptions propagating to the top of the dispatcher
for formatting.

  $ check_code="$TESTDIR"/../contrib/check-code.py
  $ cd "$TESTDIR"/..
  $ if hg identify -q > /dev/null 2>&1; then :
  > else
  >     echo "skipped: not a Mercurial working dir" >&2
  >     exit 80
  > fi
