Subject: [PATCH] cnic: Fix crash in cnic_bnx2x_service_kcq()

commit 104a43edb264321a4d41850e98153b4fa8a9ef42
    cnic: Use CHIP_NUM macros from bnx2x.h

changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE
is supported or not.  There is another place in cnic that is still using
the old method to determine if FCoE is supported or not.  The 2 methods
may not yield the same result after the network interface is brought down
and up.  This will cause the crash as cnic_bnx2x_service_kcq() will access
the uninitialized cp->kcq2.

The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which
uses the bnx2x NO_FCOE() macro.  As a follow-up, we can clean up the code
to remove the old method as it is no longer needed.
