Qu Wenruo ff1ff014f0 btrfs-progs: tests: in misc/038 test cases 
The test case always fails in my VM, with the following error:

  $ sudo TEST=038\* make test-misc
     [TEST]   misc-tests.sh
     [TEST/misc]   038-backup-root-corruption
  Backup 2 not overwritten
  test failed for case 038-backup-root-corruption

After more debugging, it turns out that there is nothing wrong except
the final check:

  [ "$main_root_ptr" -ne "$backup_new_root_ptr" ] || _fail "Backup 2 not overwritten"

The _fail() is only triggered if the previous check returns false, which
is completely the opposite.

Furthermore on the github CI, the kernel commits 2 instead of 1
transaction, resulting the next slot never to match the current
generation/tree root.

The two bugs combined, github CI always passses the test case, while
for my VM which does the expected one transaction, it would always fail.

Fix it by:

- Use a proper "if [] then; fi" block to check the tree root bytenr
- Use the generation diff to calculate the expected backup root slot
- Log the full super block dump for debug usage
