We are currently not handling RX/RSS modes correctly.
After launching testpmd with multiple RXQs, if the user tries to set
the number of RXQs to 1, driver is not updating the "hash_type"
and "hash_mode" values of the VNICs. As a result, driver issues
bnxt_vnic_rss_configure() unnecessarily and the FW command fails.
Fixed bnxt_mq_rx_configure() to update VNIC RSS fields unconditionally.
