From: Filipe Manana <fdmanana@xxxxxxxx>
The test was using $SCRATCH_MNT as a mountpoint for $SCRATCH_DEV, which
is counter intuitive and not expected by the fstests framework - this
made the test fail after commit 27d077ec0bda (common: use mount/umount
helpers everywhere). So rewrite the test to use the scratch device for
all data and use a test specific directory inside $TEST_DIR to use as a
mount point for a cross mount of $SCRATCH_DEV.
This test was also overriding $seqres.full, through the redirect ">"
operator, if a call to cp failed. Fix that by using instead the operator
">>". Also make the test use the function _mount() instead of calling
the mount program directly.
