net: pktgen: Remove unused 'allocated_skbs' field

Bogdan Hamciuc · davem330 · commit 1ce4b2f44df7 · 2015-07-29T23:00:39.000-07:00
Field pktgen_dev.allocated_skbs had been written to, but never read
from. The number of allocated skbs can be deduced anyway, from the total
number of sent packets and the 'clone_skb' param.
