xfs: rmap btree add more reserved blocks
Originally-From: Dave Chinner <dchinner@redhat.com> XFS reserves a small amount of space in each AG for the minimum number of free blocks needed for operation. Adding the rmap btree increases the number of reserved blocks, but it also increases the complexity of the calculation as the free inode btree is optional (like the rmbt). Rather than calculate the prealloc blocks every time we need to check it, add a function to calculate it at mount time and store it in the struct xfs_mount, and convert the XFS_PREALLOC_BLOCKS macro just to use the xfs-mount variable directly.
