From the e2fsck man pages, the exit codes of 0, 1, 2 should
not be treated as failures. We should never see exit code 2 though,
since it only occurs when e2fsck is run against a mounted filesystem.
The solution is to extend the check to only fail on exit code > 1.
Test Plan
PASS: Verify e2fsck exit code handling during subcloud install
with resized partition
