[XFS] fix biosize option
iosizelog shouldn't be the same as iosize but the logarithm of it. Then again the current biosize option doesn't make much sense to me as it doesn't set the preferred I/O size as mentioned in the comment next to it but rather the allocation size and thus is identical to the allocsize option (except for the missing logarithm). It's also not documented in Documentation/filesystems/xfs.txt or the mount manpage.
