[PATCH] dplayx: Map global memory anywhere if the standard address is unavailable.

There's an existing code path and ERR log that seems to assume MapViewOfFileEx
will already do this, but it doesn't. As the comments note, if this memory
winds up somewhere else, it will cause problems if more than one process is
trying to use dplay. However, the current code breaks in all circumstances
if the fixed address is unavailable.
