scsi: fnic: Fix built-in NVMe/FC build

Browse Source 
The fnic NVMe/FC code is guarded with IS_ENABLED(CONFIG_NVME_FC).  That
also evaluates true when NVME_FC is built as a module.

When fnic is built into vmlinux and NVME_FC=m, fnic_nvme.o still
references the NVMe/FC transport helpers even though those helpers are
not reachable from built-in code. The final vmlinux link then fails with
undefined nvme_fc_* symbols.

Use IS_REACHABLE(CONFIG_NVME_FC) for the fnic NVMe/FC implementation and
prototypes so built-in fnic uses the disabled stubs unless the NVMe/FC
transport is reachable.
