GFS2: Use cached rgrp in gfs2_rlist_add()
Each block which is deallocated, requires a call to gfs2_rlist_add() and each of those calls was calling gfs2_blk2rgrpd() in order to figure out which rgrp the block belonged in. This can be speeded up by making use of the rgrp cached in the inode. We also reset this cached rgrp in case the block has changed rgrp. This should provide a big reduction in gfs2_blk2rgrpd() calls during deallocation. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
