Master fails when dropping queued builds after changing revision limits

[Angel Marin <anmar@…>]

If you change revision limits to a configuration, and there are queued builds outside that limits, master throws error when trying to remove them from queue.

Exception thrown:

Traceback (most recent call last):

Patch against r372 to fix this

This has been build.rev for a long time, so this ticket is no longer an issue.
