We should cleanup vq resubmit info when set_inflight_fd
before set_vring_kick which will check if there is any
inflight io waiting for resubmission.

Otherwise, when the vm is rebooting immediately after
reconnecting to the vhost target (inflight io has not
been resubmitted yet), the vhost backend still use the
old resubmit info set when reconnection.
