vfio/common: Fix wrong %m usages
There are several places where the %m conversion is used if one of vfio_dma_map(), vfio_dma_unmap() or vfio_get_dirty_bitmap() fail. The %m usage in these places is wrong since %m relies on errno value while the above functions don't report errors via errno. Fix it by using strerror() with the returned value instead.
