	An ffs filesystem of the opposite endianness can be mounted, but
	gets a "bad file descriptor" error when trying to access the root
	of the filesystem.

>How-To-Repeat:

	walnut:~ 1# umount /archive
	walnut:~ 2# fsck_ffs -B le /dev/rwd1e
	** /dev/rwd1e

	CONVERT TO LITTLE ENDIAN? [yn] y

	** Swapped byte order
	** Last Mounted on /archive
	** Phase 1 - Check Blocks and Sizes
	** Phase 2 - Check Pathnames
	** Phase 3 - Check Connectivity
	** Phase 4 - Check Reference Counts
	** Phase 5 - Check Cyl groups
	11731 files, 9963424 used, 1291063 free (391 frags, 161334 blocks, 0.0% fragmentation)

	***** FILE SYSTEM WAS MODIFIED *****
	walnut:~ 3# mount /dev/wd1e /archive
	walnut:~ 4# ls /archive
	ls: /archive: Bad file descriptor
	Exit 1
	walnut:~ 5# umount /archive
	walnut:~ 6# fsck_ffs -B be /dev/rwd1e
	** /dev/rwd1e

	CONVERT TO BIG ENDIAN? [yn] y

	** Last Mounted on /archive
	** Phase 1 - Check Blocks and Sizes
	** Phase 2 - Check Pathnames
	** Phase 3 - Check Connectivity
	** Phase 4 - Check Reference Counts
