[XFS] Kill off xfs_statvfs.
We were already filling the Linux struct statfs anyway, and doing this trivial task directly in xfs_fs_statfs makes the code quite a bit cleaner. While I was at it I also moved copying attributes that don't change over the lifetime of the filesystem outside the superblock lock. xfs_fs_fill_super used to get the magic number and blocksize through xfs_statvfs, but assigning them directly is a lot cleaner and will save some stack space during mount.
