x86/shadow: don't use PV LDT area for cross-pages access emulation

As of 703ac3a ("x86: introduce create_perdomain_mapping()"), the page
tables for this range don't get set up anymore for non-PV guests. And
the way this was done was marked as a hack rather than a proper
mechanism anyway. Use vmap() instead.
