LU-14119 osd-zfs: enable LUDA_VERIFY

In osd_dir_it_rec(), if dirent is successfully got, and the FID in
dirent is sane, it returns right away, however if
LUDA_VERIFY|LUDA_VERIFY_DRYRUN is set, the FID in dirent should be
compared with the FID in LMA, and replaced with the latter one if
they are differet.
