radv: fix format feature reporting for modifiers
The format_feature_flags bitfield is derived from the modifier if the tiling is set to VK_IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT. However radv will reset the tiling to either LINEAR or OPTIMAL if the caller supplied a VkPhysicalDeviceImageDrmFormatModifierInfoEXT in the chain.
Stop resetting the tiling, so that we can compute the correct feature flags.
