[PATCH v2 compass-ci] git_mirror.rb: fix that the priority with priority queue may be negative
Priority queue use the priority to decide which one pop first, and small priority one would be pop first.
And the more active repo should be pop first, so priority of repo would minus its new ref times to make its priority small.
But some times, the result can be negative, this make the repo delayed a lot.

why not use the negative number, but reset the priority level number?

Because the priority_queue can not support negative number well.
Thanks, Yuanchao
