bnxt_en: Do not use the CNP CoS queue for networking traffic.
The CNP CoS queue is reserved for internal RDMA Congestion Notification
Packets (CNP) and should not be used for a TC. Modify the CoS queue
discovery code to skip over the CNP CoS queue and to reduce
bp->max_tc accordingly. However, if RDMA is disabled in NVRAM, the
the CNP CoS queue can be used for a TC.
