ivhsmem: read do not accept more than sizeof(long)
ivshmem_read() only reads sizeof(long) from the input buffer. Accepting more could lead to fifo8 abort() on 32bit systems if fifo is not empty. A following patch will change the protocol to 64-bit little-endian instead. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Claudio Fontana <claudio.fontana@huawei.com>
