The last parameter should be REFPROPVARIANT instead of PROPVARIANT.

The Vulkan specification does not currently mandate this. However, an
(unfortunately internal) Khronos discussion determined that this is an
oversight, and that many drivers likely expect that no counter buffer will be
bound if no XFB buffer is bound. Accordingly the specification will probably
mandate this in the future.

lavapipe is such a driver. This fixes a crash with llvmpipe in
test_index_buffer_offset().

If DISCARD maps are accelerated, passing empty map flags won't return the same accelerated BO.

Tested with Port Royale 2 and Rayman 3.

Fixes incorrect EG key number scale and offset that caused missing
lower notes of some instruments (e.g. Acoustic Grand Piano).

This allows loaded instruments to take effect without a subsequent
program change. In particular, when there is no program change at all,
this allows the default Acoustic Grand Piano or Standard drum set to
play. As a side effect, this disables FluidSynth fallback logic for
missing presets.

Instead of checking it in set_report_from_joystick_event.

This prevents Native Instruments Kontakt 7 from crashing on start-up.
