xfs/270: Fix syntax error

Without xfsprogs commit
f4afdcb0a ("xfs_db: clean up the salvage read callsites in set_cur()"),
this case will fail as below:

+/var/lib/xfstests/tests/xfs/270: line 51: [: !=: unary operator expected

With this xfsprogs bug, xfs_db can't get new_ro_compat value, so report
this bash syntax error.

Fix this and add a helper output for xfsprogs bug.
