xfs: update max log size
Commit a6634fba3dec4a92f0a2c4e30c80b634c0576ad5 in xfsprogs increased the maximum log size supported by mkfs. Merged back the changes to xfs_fs.h so the growfs enforced the same limit and the headers are in sync. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Eric Sandeen <sandeen@sandeen.net>
