How to deal with upside-down insulation?
Nearly all of Virginia is considered to be in the "mixed-humid" zone.  On an annual average, moisture migration is fairly evenly distributed (alternating toward the interior and toward the exterior).  

Moist air tends to migrate toward the cold side of a wall.  The vapor retarder is installed correctly, in your crawl space, to discourage exterior humidity from migrating toward the interior, during the Summer, especially if air-conditioning is used.

By maintaining space between the un-faced side of the batt insulation and the ceiling drywall (R-19 in a 2x8 stud bay with faced-side stapled to top of Floor Joists [FJ's]), an air channel was created to facilitate drying (of sorts) via the wood FJs.

In areas (climates) that have a distinct Summer vs Winter there is a good chance (depending on humidity, the use of air-conditioning, and moisture permeability of the structure's siding material) that the air retarder of batt insulation will be on the "wrong" side of the building's heating/cooling envelope half the time.

One reason why old (19th Century U.S.) homes don't suffer from moisture damage, mold, mildew in the exterior wall cavities (unless caused by some drainage or structural failure) is that the wall cavities either had no insulation or the insulation (sawdust, newspapers, sheep's wool, etc.) permitted fairly quick drying of the wall cavity.
