Log Message:
Fix the LIST_MOVE macro to properly update the back-pointer of the
first entry in the list.
Note that the signature of LIST_MOVE() macro also changes (it grew an
additional argument). This should not require a kernel version bump
since nothing appears to use LIST_MOVE() other than the recently added
atf test.
