In function rg_mblk_search, it's searching for multiple blocks in a given state (e.g. "free"). If there's an active block reservation its goal is the next free block of that. If the resource group contains the dinode's goal block, that's used for the search. But if neither is the case, it uses the rgrp's last allocated block. That way, consecutive allocations appear after one another on media. The problem comes in when you hit the end of the rgrp; it would never start over and search from the beginning. This became a problem, since if you deleted all the files and data from the rgrp, it would never start over and find free blocks. So it had to keep searching further out on the media to allocate blocks. This patch resets the rd_last_alloc after it does an unsuccessful search at the end of the rgrp.
