Firmware resources are queried in lpfc_sli4_read_config(). The driver parameters cfg_irq_chann and cfg_hdw_queue are adjusted from defaults if constrained by firmware resources. The minimum resource check includes a special allocation for queues such as ELS, MBOX, NVME LS. However the additional reservation was also incorrectly applied to EQ resources. Reordered WQ|CQ|EQ resource checks to apply the special allocation adjustment to WQ and CQ resources only.
