    'NBD_DISCONNECT' first, however, following message was found: block nbd0: Send disconnect failed -32 Which
    indicate that something is wrong with the server. Then, qemu-nbd -d will call ioctl 'NBD_CLEAR_SOCK',
    however ioctl can't clear requests after commit 2516ab1543fd(nbd: only clear the queue on device
    teardown). And in the meantime, request can't complete through timeout because nbd_xmit_timeout() will
    always return 'BLK_EH_RESET_TIMER', which means such request will never be completed in this situation.
    Now that the flag 'NBD_CMD_INFLIGHT' can make sure requests won't complete multiple times, switch back to
    call nbd_clear_sock() in nbd_clear_sock_ioctl(), so that inflight requests can be cleared.
