Sagi Grimberg fb8658581a nvmet-tcp: fix uninitialized variable access
If we end up in nvmet_tcp_try_recv_one with a bogus state
queue receive state we will access result which is uninitialized.

Initialize restult to 0 which will be considered as if no data
was received by the tcp socket.

Fixes: 872d26a391da ("nvmet-tcp: add NVMe over TCP target driver")
