Lennart Poettering 36c4dc089e core: change emergency_action() to return void
The function so far always returned -ECANCELLED, which is ignored in all
cases the function is invoked, except one: in unit_test_start_limit()
where -ECANCELLED is returned when the start limit is hit, which is part
of unit_start()'s protocol of return values.

Since the emergency_action() logic should be relatively generic and is
used in many places, let's drop the return value from it, since it's
constant anyway, and in alll cases useless. Instead, let's return it in
unit_test_start_limit(), where it's part of the protocol.

No change in behaviour.
