ext4: Widen type of ext4_sb_info.s_mb_maxs[]
I chased the cause of following ext4 oops report which is tested on
ia64 box.
http://bugzilla.kernel.org/show_bug.cgi?id=12018
The cause is the size of s_mb_maxs array that is defined as "unsigned
short" in ext4_sb_info structure. If the file system's block size is
8k or greater, an unsigned short is not wide enough to contain the
value fs->blocksize << 3.
