bnxt_en: Pass NQ ID to the FW when allocating RX/RX AGG rings

Newer firmware can use the NQ ring ID associated with each RX/RX AGG
ring to enable PCIe Steering Tags on P5_PLUS chips.  When allocating
RX/RX AGG rings, pass along NQ ring ID for the firmware to use.  This
information helps optimize DMA writes by directing them to the cache
closer to the CPU consuming the data, potentially improving the
processing speed.  This change is backward-compatible with older
firmware, which will simply disregard the information.
