alarms will not get cleared in a particular case

The domain alarms do not get cleared in the particular
case in which there is more than one alarm to be
cleared by oh_remove_alarms() and the first match does
not match the additional property of deassert mask. If
that happens, subsequent alarms thay may match
completely will not be found and cleared.

The logic must be reworked in oh_remove_alarms to avoid
this bug.
