generic/373 and generic/374 test that cross-mountpoint reflink/dedupe fail with EXDEV. For this test, _scratch_mount is called a 2nd time with same mount arguments, but a different value of SCRATCH_MNT. This practice is incorrect for overlayfs, which should not be using the same upper/work dirs on two different overlay super blocks. Change the test to use bind mount instead, which results in the expected setup for both block device mount and overlay mount.
