nvme-tcp: fix nvme_tcp_term_pdu to match spec

Browse source 
The FEI field of C2HTermReq/H2CTermReq is 4 bytes but not 4-byte-aligned
in the NVMe/TCP specification (it is located at offset 10 in the PDU).
Split it into two 16-bit integers in struct nvme_tcp_term_pdu
so no padding is inserted. There should also be 10 reserved bytes after.
There are currently no users of this type.
