tg3: restore rx_dropped accounting
commit 511d22247be7 (tg3: 64 bit stats on all arches), overlooked the
rx_dropped accounting.
We use a full "struct rtnl_link_stats64" to hold rx_dropped value, but
forgot to report it in tg3_get_stats64().
Use an "unsigned long" instead to shrink "struct tg3" by 176 bytes, and
report this value to stats readers.
Increment rx_dropped counter for oversized frames.
