net: ravb: Fix RX byte accounting for jumbo packets
 
The RX byte accounting for jumbo packets was changed to fix a potential
use-after-free bug. However, that fix used the wrong variable and so
only accounted for the number of bytes in the final descriptor, not the
number of bytes in the whole packet.

To fix this, we can simply update our stats with the correct number of
bytes before calling napi_gro_receive().

Also rename pkt_len to desc_len in ravb_rx_gbeth() to avoid any future
confusion. The variable name pkt_len is correct in ravb_rx_rcar() as
that function does not handle packets spanning multiple descriptors.
