nvme: Add PCI transport type
Define the transport type NVMF_TRTYPE_PCI for PCI endpoint targets.
This transport type is defined using the value 0 which is reserved in
the NVMe base specifications v2.1 (Figure 294). Given that struct
nvmet_port are zeroed out on creation, to avoid having this transsport
type becoming the new default, nvmet_referral_make() and
nvmet_ports_make() are modified to initialize a port discovery address
transport type field (disc_addr.trtype) to NVMF_TRTYPE_MAX.
Any port using this transport type is also skipped and not reported in
the discovery log page (nvmet_execute_disc_get_log_page()).
The helper function nvmet_is_pci_ctrl() is also introduced to check if
a target controller uses the PCI transport.
