I think that using the macro makes code more clearly, and it's more
convenient to use the macro than the original "|=", "&=" and "&" things.
And, no more harder for reading and grepping, just omit the "XFS_MOUNT_".

BTW, these macros were borrowed from Btrfs. I myself like it, but if
you XFS guys all do not like, I can drop it.

Thanks,
