a harmless typo in ifo_read.c, libdvdread

I think I've found a harmless typo from line# 1633 and 1634 of 
ifo_read.c (cvs), libdvdread.

ifoRead_PGCIT_internal():
 
  for(i = 0; i < pgcit->nr_of_pgci_srp; i++) {
    memcpy(&pgcit->pgci_srp[i], ptr, PGCI_LU_SIZE); /* line# 1633 */
    ptr += PGCI_LU_SIZE; /* line# 1634 */
    B2N_16(pgcit->pgci_srp[i].ptl_id_mask);
    B2N_32(pgcit->pgci_srp[i].pgc_start_byte);
    CHECK_VALUE(pgcit->pgci_srp[i].unknown1 == 0);
  }

Should the "PGCI_LU_SIZE" of above be "PGCI_SRP_SIZE"?
Well, it doesn't hurt since they both are defined as 8.
