[PATCH v5 4/8] softmmu: xen: Always pass offset + addr to xen_map_cache

[Edgar E. Iglesias]

From: "Edgar E. Iglesias" <edgar.igles...@amd.com>

Always pass address with offset to xen_map_cache().
This is in preparation for support for grant mappings.

Since this is within a block that checks for offset == 0,
this has no functional changes.
