Latest commit c0d0e35 Mar 10, 2017 @OGAWAHirofumi OGAWAHirofumi committed with fat: fix using uninitialized fields of fat_inode/fsinfo_inode
Recently fallocate patch was merged and it uses
MSDOS_I(inode)->mmu_private at fat_evict_inode().  However,
fat_inode/fsinfo_inode that was introduced in past didn't initialize
MSDOS_I(inode) properly.

With those combinations, it became the cause of accessing random entry
in FAT area.
