qcacmn: Add GRO support to NAPI+Rx_thread processing model

GRO aggregations are hanging out of NAPI instance and we cannot use the
hif NAPI instance in Rx thread as gro_list inside NAPI is flushed out
at the start and end of NAPI poll, this will corrupt the gro_list on
which rx_thread is working. Address this concern by creating dummy
NAPI instances mapping to each hif NAPI and by not scheduling them.
