The pci only stuff goes in 'struct nvme_dev' and embeds 'struct
nvme_ctrl', but fabrics gets to use nvme_ctrl directly?
If we need transport specifics for anything, like you have during
nvme_init_identify, I think we should add function callbacks to
nvme_ctrl_ops to set up those specifics, then we don't need 'is_fabrics'
checks.
