This is a fix for segfault issue, because of usage of uninitialized vkQueue handle.
Spec 1 states that vkGetDeviceQueue must only be used to get queues that were created with the flags parameter of VkDeviceQueueCreateInfo set to zero. To get queues that were created with a non-zero flags parameter use vkGetDeviceQueue2.
The problem that in case queue was created with flags set to zero following vkGetDeviceQueue2 call will fail. By failing I mean that pQueue set to NULL, which later leads to segfault.
This problem was also reported by vulkan validation layer:
vkr: vkGetDeviceQueue2: value of pQueueInfo->flags must not be 0. The Vulkan spec states: flags must not be 0 (https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VUID-VkDeviceQueueInfo2-flags-requiredbitmask)
