LU-15643 osd-ldiskfs: don't trigger scrub on irreparable FIDs

In osd_fid_lookup(), if the FID mapping found in OI table is insane,
it will be added into a list called os_inconsistent_items, and OI
scrub will be triggered.

Later if OI scrub can't fix this mapping, it should move this mapping
into a list called os_stale_items, and subsequent access of the same
FID should return -ESTALE immediately, other than trigger OI
scrub repeatedly.

Add sanity-scrub 20. Remove sanity-scrub 1d, which is not a sane test
because it altered FID in LMA, which is the last to trust for an
object, and it could pass just by chance.
