The current code makes assumptions about the CID (context ID) memory
space and starting CID that may not be always correct when firmware
changes.  In particular, BNX2_ISCSI_START_CID may not always be fixed.
We now calculate cp->max_cid_space and cp->iscsi_start_cid dynamically
instead of using fixed constants.  The unused cp->max_iscsi_conn is also
eliminated.

By creating a common data stucture kcq_info for all devices, the kcq
(kernel completion queue) for all devices can be allocated by common
code.
