monitor: Separate QUORUM_REPORT_BAD events according to the node name 

The QUORUM_REPORT_BAD event is emitted whenever there's an I/O error
in a child of a Quorum device. This event is emitted at a maximum rate
of 1 per second. This means that an error in one of the children will
mask errors in the other children if they happen within the same 1
second interval.

This patch modifies qapi_event_throttle_equal() so QUORUM_REPORT_BAD
events are kept separately if they come from different children.
