[PATCH v2 3/7] affs: remove useless superblock writeout on remount

[Artem Bityutskiy]

From: Artem Bityutskiy <artem.bityutskiy@xxxxxxxxxxxxxxx>

We do not need to write out the superblock from '->remount_fs()' because
VFS has already called '->sync_fs()' by this time and the superblock has
already been written out. Thus, remove the 'affs_write_super()'
infocation from 'affs_remount()'.
