scsi: lpfc: fix linking against modular NVMe support

commit cd069bb9f9ff13b23492fda6ccdb458ac4f641ca upstream.

When LPFC is built-in but NVMe is a loadable module, we fail to link the
kernel:

drivers/scsi/built-in.o: In function `lpfc_nvme_create_localport':
(.text+0x156a82): undefined reference to `nvme_fc_register_localport'
drivers/scsi/built-in.o: In function `lpfc_nvme_destroy_localport':
(.text+0x156eaa): undefined reference to `nvme_fc_unregister_remoteport'

We can avoid this either by forcing lpfc to be a module, or by disabling
NVMe support in this case. This implements the former.
