[XFS] Fix block reservation mechanism.
The block reservation mechanism has been broken since the per-cpu superblock counters were introduced. Make the block reservation code work with the per-cpu counters by syncing the counters, snapshotting the amount of available space and then doing a modifcation of the counter state according to the result. Continue in a loop until we either have no space available or we reserve some space.
