Commit 27d077ec0bda (common: use mount/umount helpers everywhere) made
a few btrfs test fail for 2 different reasons:
1) Some tests (btrfs/029 and btrfs/031) use $SCRATCH_MNT as a mount
point for some subvolume created in $TEST_DEV, therefore calling
_scratch_unmount does not work as it passes $SCRATCH_DEV as the
argument to the umount program. This is intentional to test reflinks
accross different mountpoints of the same filesystem but for different
subvolumes;
2) For multiple devices filesystems (btrfs/003 and btrfs/011) that test
the device replace feature, we need to unmount using the mount path
($SCRATCH_MNT) because unmounting using one of the devices as an
argument ($SCRATCH_DEV) does not always work - after replace operations
we get in /proc/mounts a device other than $SCRATCH_DEV associated
with the mount point $SCRATCH_MNT (this is mentioned in a comment at
btrfs/011 for example), so we need to pass that other device to the
umount program or pass it the mount point.
Using $SCRATCH_MNT as a mountpoint for a device other than $SCRATCH_DEV is
misleading, but that's a different problem that existed long before and
this change attempts only to fix the regression from 27d077ec0bda, leaving
such cleanups to later.
Fix this by making _sctatch_unmmount() pass $SCRATCH_MNT to umount instead
of $SCRATCH_DEV.

V2: Change _sctatch_unmount() to pass $SCRATCH_MNT as the argument to the
umount program instead of $SCRATCH_DEV. This makes the btrfs tests
pass again.
