rootfs-block: avoid remount when options don't change

Mounting, unmounting and then mounting a disk partition takes some
time.

On embedded systems such as OLPC XO where we disable fsck and fstab
reading, the root options are not going to change throughout the
mount_root() function, so remounting is time consuming and without
change.

Detect and optimize for this case so that the filesystem is only
mounted once.
