scsi: osst: silence underflow warning in osst_verify_frame()
The code looks like this: i = ntohl(aux->filemark_cnt); if (STp->header_cache != NULL && i < OS_FM_TAB_MAX && (i > STp->filemark_cnt || STp->first_frame_position - 1 != ntohl(STp->header_cache->dat_fm_tab.fm_tab_ent[i]))) { If i is negative then it's less than OS_FM_TAB_MAX so we read before the start of the STp->header_cache->dat_fm_tab.fm_tab_ent[] array.
