vhost/nvme: remove VHOST_USER_NVME_IO_CMD socket message

Browse Source 
VHOST_USER_NVME_IO_CMD is designed to deliver NVMe IO command
header to slave target via socket, this can be used in BIOS
which will not enable Shadow Doorbell Buffer feature, since
we enabled the shadow BAR feature to support some old Guest
kernel without Shadow Doorbell Buffer feature, so the message
isn't required, just remove it.
