Botond Dénes 354c805e6a reader_permit: remove check_abort() ...

This method can cause performance regressions if used in the wrong place
-- namely if it is used to abort reads by throwing the abort exception.
Exceptions should be propagated during reads without throwing them,
otherwise they cause extra CPU load, making a bad situation worse.
Remove this method, so it doesn't accidentally get more users, migrate
remaining users to get_abort_exception().
