        src/sys/dev/pci: virtio_pci.c

Log Message:
virtio@pci: Nix useless sc_mapped_iosize.

This appears to have been a mistaken attempt to pass the subregion
length through to bus_space_unmap, which doesn't make any sense --
bus_space_subregion does not allocate anything and the resulting
handle must not be passed to bus_space_unmap.

Once we pass the size that was actually returned by pci_mapreg_map to
bus_space_unmap, which matches the size passed internally by
pci_mapreg_map to bus_space_map, sc_mapped_iosize is no longer used
and can be flushed.

Prompted by PR kern/58335.
