Fix DPDK-3276: reopen set port 0 vf rxmode BAM on failed
When reopen set port 0 vf rxmode BAM on, vm can't receive packets, because
RX buffer is full on host when host receives too many packets if host only
run testpmd without "start" command.
RX buffer will be cleaned just when start forward packets.
If we not run "start", rx buffer will be full, and can't receive new packets.
In this case, we don't want pf forwarding packets, so we set fwd rxonly, and
start forwarding on host.
