Specifying a file in an EXT4 or FAT partition on a virtio device as environment location failed because virtio hadn't been initialized by the time the environment was loaded. This patch mirrors commit 54ee5ae84191 ("Add SCSI scan for ENV in EXT4 or FAT") in issue and fix, just for a different kind of block device. The additional include in include/virtio.h is needed so all functions called there are defined, the alternative would have been to include dm/device.h separately in the env/ sources. Checkpatch suggests using "if (IS_ENABLED(CONFIG...))" instead of "#if defined(CONFIG_...)", I'm sticking to the style of the existing code here.
