Dmitry Kravkov 134d0f974c bnx2x: fix cl_id allocation for non-eth clients for NPAR mode 
There are some consolidations of NPAR configuration
when FCoE and iSCSI L2 clients will get the same id,
in this case FCoE ring will be non-functional.

* The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is

* as the FCoE queue do not require a FP-SB and other components like
* the CNIC may consume FP-SB reducing the number of possible L2 queues
*
* If the maximum number of FP-SB available is X then:
* a. If CNIC is supported it consumes 1 FP-SB thus the max number of
* regular L2 queues is Y=X-1
* b. in MF mode the actual number of L2 queues is Y= (X-1/MF_factor)
* c. If the FCoE L2 queue is supported the actual number of L2 queues
* is Y+1
* d. The number of irqs (MSIX vectors) is either Y+1 (one extra for
* slow-path interrupts) or Y+2 if CNIC is supported (one additional
* FP interrupt context for the CNIC).
* e. The number of HW context (CID count) is always X or X+1 if FCoE
* L2 queue is supported. the cid for the FCoE L2 queue is always X.
