scsi: lpfc: fix unused variable warning

Browse Source 
The newly introduced 'cpu' variable is only used inside of an optional
block, so we get a warning without CONFIG_SCSI_LPFC_DEBUG_FS:

drivers/scsi/lpfc/lpfc_nvme.c: In function 'lpfc_nvme_io_cmd_wqe_cmpl':
drivers/scsi/lpfc/lpfc_nvme.c:968:30: error: unused variable 'cpu' [-Werror=unused-variable]
  uint32_t code, status, idx, cpu;

Move the declaration into the same block to avoid the warning.

Fixes: 63df6d637e ("scsi: lpfc: Adapt cpucheck debugfs logic to Hardware Queues")
