[PATCH 04/14] net/bnxt: use the correct COS queue for Tx

[Ajit Khaparde]

Earlier the firmware was configuring single lossy COS profiles for Tx.
But now more than one profiles is possible.
Identify the profile a NIC driver should use based on the profile type
hint provided in queue_cfg_info.

If the firmware does not set the bit to use profile type,
then we will use the older method to pick the COS queue for Tx.
