libxfs: Fix a couple of sparse complaintis

Source kernel commit: 5089eafffba2ed444789e5d25c7c0dfd62595713

No significant changes, just silence a couple of sparse errors.

Using cpu_to_be32(NULLAGINO), the NULLAGINO constant will be encoded in
BE as a constant, avoiding a BE -> CPU conversion every iteraction of
the loop, if be32_to_cpu(agi->agi_unlinked[i]) was used instead.
