Handle FLUSH errors as "expected"

Before openzfs#16061 zio_vdev_io_done() was not used for FLUSH requests. Addition of it triggers reprobe each TXG for vdevs not supporting them. Since those errors are often expected, they are normally handled by individual vdev drivers and should be ignored here.
