bnxt_en: Workaround Nitro A0 hardware RX bug (part 1).
Nitro A0 has a hardware bug in the rx path. The workaround is to create
a special COS context as a path for non-RSS (non-IP) packets. Without this
workaround, the chip may stall when receiving RSS and non-RSS packets.
Add infrastructure to allow 2 contexts (RSS and CoS) per VNIC. Allocate
and configure the CoS context for Nitro A0.
