For a long time this test has been failing on all kinds of VM configuration,
which are using virtio_blk devices. This is due to the fact that scsi
devices are deletable and virtio_blk are not. However, this only prevents
device replace case to run and has no negative effect on the other
useful test cases.

Re-enable btrfs/003 to run by making _require_deletable_scratch_dev_pool
private to the test case and modifying it to return success (0) or
failure (1) if devices are not deletable. Further modify the replace
test case to check the return value of this function and skip it if
devices are not deletable.

Changes since v1: 
 * Rename the function to deletable_scratch_dev_pool
