scsi: lpfc: Adapt cpucheck debugfs logic to Hardware Queues

Browse Source 
Similar to the io execution path that reports cpu context information, the
debugfs routines for cpu information needs to be aligned with new hardware
queue implementation.

Convert debugfs cnd nvme cpucheck statistics to report information per
Hardware Queue.
