xfs: pass full xfs_dqblk to repair during quotacheck

xfs: pass full xfs_dqblk to repair during quotacheck

Source kernel commit: 48fa1db87f730da1aed2d3df0cc8c33c7c133b4b

It's a bit dicey to pass in the smaller xfs_disk_dquot and then cast it to
something larger; pass in the full xfs_dqblk so we know the caller has sent
us the right thing.  Rename the function to xfs_dqblk_repair for
clarity.
