btrfs/146: remove unnecessary scratch unmount to avoid test failure

Right at the beginning of the test we are unmonting the scratch device,
however at this point the device was never mounted, so the unmount fails
with an error message like the following:

  umount: /home/fdmanana/btrfs-tests/scratch_1: not mounted

Which is not expected by the golden output and therefore causes the test
to fail.

Since the device/mount point was not mounted yet in the test, and since
the test framework unmounts the scratch device after each test finishes,
just remove the call to _scratch_unmount.
