We service 2 queues (kcq1 and kcq2) in cnic_service_bnx2x_bh().  If
the status block index has changed when servicing the kcq2, we must
go back and check kcq1.  The latest status block index will be used
to acknowledge the interrupt, and without looping back to check kcq1,
we may miss events on kcq1.
