1b4e5497d3 vfio/common: Fix incorrect address alignment in vfio_dma_map_ram_section 
The 'iova' will be passed to host kernel for mapping with the
HPA. It is related to the host page size. So TARGET_PAGE_ALIGN
should be replaced by REAL_HOST_PAGE_ALIGN. In the case of
large granularity (64K), it may return early when map MMIO RAM
section. And because of the inconsistency with
vfio_dma_unmap_ram_section, it may cause 'assert(qrange)'
in vfio_dma_unmap.
