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.

I originally sent the patch in March 2013, the day after the broken
patch made it into Linux-next. Unfortunately there was some
misunderstanding about it (James Smart thought the broken patch
was the correct version), and my fix never got merged.
