[PATCH v1 8/9] ext4: small cleanup in ext4_commit_super

[Artem Bityutskiy]

From: Artem Bityutskiy <artem.bityutskiy@xxxxxxxxxxxxxxx>

We have many 'EXT4_SB(sb)' references in 'ext4_commit_super()' and I am going
to add another one, so I think the function will be a bit tidier if I introduce
a separate 'sbi' pointer for the ext4 superblock.
