LU-14448 lod: verify LOV early in lod_get_default_striping

lod_get_default_striping() will get both default LOV and default LMV,
and parse them to struct lod_default_striping one by one, however the
LOV and LMV data are both stored in lod_thread_info.lti_ea_store, so
lod_verify_striping() should verify LOV upon getting LOV, otherwise
if both exists, it's LMV that's verified, which will return -EINVAL.
