btrfs-progs: Use fs_info instead of root for BTRFS_MAX_XATTR_SIZE
Do a cleanup. Also make it consistent with kernel. Use fs_info instead
of root for BTRFS_MAX_XATTR_SIZE, since maybe in some situation we do
not know root, but just know fs_info.
To be consistent with kernel, change macro to inline function.
