scsi: lpfc: Fix WQ|CQ|EQ resource check

Adapter configurations with limited EQ resources may fail to initialize.

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.
