nvmet-tcp: handle TCP_CLOSING state in nvmet_tcp_state_change

Browse Source 
When an NVMe/TCP connection shuts down, the underlying TCP socket can
enter the TCP_CLOSING state (state 11).  Currently, the
nvmet_tcp_state_change() callback does not explicitly handle this state,
which results in harmless but noisy kernel warnings:

nvmet_tcp: queue 2 unhandled state 11

Add TCP_CLOSING to the switch statement alongside TCP_FIN_WAIT2 and
TCP_LAST_ACK to silently ignore the state transition.
