Subject: [PATCH 1/2] scsi: lpfc: avoid an unused function warning

The only reference to lpfc_nvmet_replenish_context() is inside of
an #ifdef, leading to a harmless warning when CONFIG_NVME_TARGET_FC
is disabled:

drivers/scsi/lpfc/lpfc_nvmet.c:1457:1: error: 'lpfc_nvmet_replenish_context' defined but not used [-Werror=unused-function]

This replaces the preprocessor conditional with a C condition,
so the compiler can see that the function is intentionally unused.

Fixes: 9a38e4f1c82f ("scsi: lpfc: Fix MRQ > 1 context list handling")
