Btrfs: use the transactions block_rsv for the csum root
The alloc warnings everybody has been seeing is because we have been reserving space for csums, but we weren't actually using that space. So make get_block_rsv() return the trans->block_rsv if we're modifying the csum root. Also set the trans->block_rsv to NULL so that if we modify the csum root when running delayed ref's that comes out of the global reserve like it's supposed to. With this patch I'm not seeing those alloc warnings anymore. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>
