vfio/pci: Fix a potential memory leak in vfio_listener_region_add
When there is an failure in vfio_listener_region_add() and the section
belongs to a ram device, there is an inaccurate error report which should
never be related to vfio_dma_map failure. The memory holding err is also
incrementally leaked in each failure.
Fix it by reporting the real error and free it.
