contrib/vhost-user-blk: avoid g_return_val_if() input validation
Do not validate input with g_return_val_if(). This API is intended for checking programming errors and is compiled out with -DG_DISABLE_CHECKS. Use an explicit if statement for input validation so it cannot accidentally be compiled out.
