Not sure what this test case wanted to achieve by deleting the
source device before the replace.
As per the comments the objective of this test case seems to be
~~~~
btrfs device replace test on RO fs
Regression test for commit:
bbb651e Btrfs: don't allow the replace procedure on read only filesystems
~~~~~
Also there won't be EIO when you delete a loop device when its
still mounted. as shown below.
mount /dev/loop0 /mnt
losetup -d /dev/loop0
echo $?
0
dd if=/dev/zero of=/mnt/tf1 count=1
1+0 records in
1+0 records out
512 bytes (512 B) copied, 0.00192936 s, 265 kB/s
cd /mnt
sync
losetup -a
/dev/loop0: [0802]:1291816 (/root/testdev/disk1)
No errors in the dmesg as well.
Instead of further confusing, I am deleting the delete loop device part

Currently we're checking file system consistency on TEST_DEV after every
successful test run even though the TEST_DEV might not even be used in
that test.
Fix it by introducing _require_test to for the test ti indicate that
it's about to use TEST_DEV.
Also add _require_test to the new script so that this requirement is a
default.
