[GFS2] Replace rgrp "recent list" with mru list
This patch removes the "recent list" which is used during allocation and replaces it with the (already existing) mru list used during deletion. The "recent list" was not a true mru list leading to a number of inefficiencies including a "next" function which made scanning the list an order N^2 operation wrt to the number of list elements. This should increase allocation performance with large numbers of rgrps. Its also a useful preparation and cleanup before some further changes which are planned in this area.
