Speed up journal recovery in userspace by avoiding a pointless
unconditional ext2_flush() call. Also made ext2_flush() more
efficient when the superblock is modified after the filesystem has
been flushed, and make it clear the superblock dirty flag
after doing the superblock/block group descriptor flush.
