Handle FLUSH errors as "expected"

Browse Source 
Before #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.
