[PULL 02/63] hw/virtio: Propagate page_mask to vhost_vdpa_listener_skipped_section()

[Michael S. Tsirkin]

From: Philippe Mathieu-Daudé <phi...@linaro.org>

In order to make vhost-vdpa.c a target-agnostic source unit,
we need to remove the TARGET_PAGE_SIZE / TARGET_PAGE_MASK /
TARGET_PAGE_ALIGN uses. TARGET_PAGE_SIZE will be replaced by
the runtime qemu_target_page_size(). The other ones will be
deduced from TARGET_PAGE_SIZE.

Since the 3 macros are used in 3 related functions (sharing
the same call tree), we'll refactor them to only depend on
TARGET_PAGE_MASK.

Having the following call tree:

  vhost_vdpa_listener_region_del()
    -> vhost_vdpa_listener_skipped_section()
       -> vhost_vdpa_section_end()

The first step is to propagate TARGET_PAGE_MASK to
vhost_vdpa_listener_skipped_section().
