[PATCH] vfio/pci: Fix sparse warning in vfio_pci_core_get_iomap()

[Matt Evans]

Use IOMEM_ERR_PTR() when returning a void __iomem * rather than
ERR_PTR().  This fixes a sparse warning, "different address spaces".

Fixes: 859dc0f6253b ("vfio/pci: Replace vfio_pci_core_setup_barmap() with vfio_pci_core_get_iomap()")
