radv: do not abort with unknown/unimplemented descriptor types

To workaround a crash with Wolfeinstein Younglood because the
games creates one descriptor with
VK_DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_NV...

I reported the problem to Machine Games, but still no answer, so
let's remove the unreachable calls (which are technically not
unreachable for buggy apps) to help gamers.

Note that AMDVLK and AMDGPU-PRO don't crash because they ignore
unsupported descriptor types.
