The function domain_page_map_to_mfn can be used to translate a virtual
address mapped by both map_domain_page and map_domain_page_global.
The former is using vmap to map the mfn, therefore domain_page_map_to_mfn
will always fail because the address is not in DOMHEAP range.

Check if the address is in vmap range and use __pa to translate it.

This patch fix guest shutdown when the event fifo is used.
