GFS2: Implement a "rgrp has no extents longer than X" scheme
With the preceding patch, we started accepting block reservations smaller than the ideal size, which requires a lot more parsing of the bitmaps. To reduce the amount of bitmap searching, this patch implements a scheme whereby each rgrp keeps track of the point at this multi-block reservations will fail.
