xen_invalidate_map_cache_entry is not expected to run in a
coroutine. Without this, there is crash:

Hi!  Is this a stable material? (It applies cleanly and builds on 8.2 and 7.2)

Actually for 7.2 it needed a minor tweak:

-void coroutine_mixed_fn xen_invalidate_map_cache_entry(uint8_t *buffer)
+void xen_invalidate_map_cache_entry(uint8_t *buffer)

but the rest is okay.
