[d3d11] Cache raw mapped pointer rather than allocation object

Browse Source 
Reduces ref counting overhead again and matches previous behaviour.

We should probably do something about the possible case of deferred context
execution with MAP_WRITE_DISCARD followed by MAP_WRITE_NO_OVERWRITE on the
immediate context, but we haven't seen a game rely on this yet.
