cluster/afr: Fix bug-1586020-mark-dirty-for-entry-txn-on-quorum-failu…

…re.t

Problem:
In line #13 of the test case, it checks whether the file is present
on first 2 bricks or not. If it is not present on even one of the bricks
it will break the loop and checks for the dirty marking on the parent
on the 3rd brick and checks for file not present on the 1st and 2nd
bricks. The below scenario can happen in this case:
- File gets created on 1st and 3rd bricks
- In line #13 it sees file is not present on both 1st & 2nd bricks and
  breaks the loop
- In line #51 test fails because the file will be present on the 1st brick
- In line #53 test will fail because the file creation was not failed on
  quorum bricks and dirty marking will not be there on the parent on 3rd
  brick

Fix:
Don't break from the loop if file is present on either brick 1 or brick 2.
