Fix an ASSERT() crash in ExternalFence SyncWaitFd(). https://registry.khronos.org/vulkan/specs/latest/man/html/vkGetFenceFdKHR.html If pGetFdInfo->handleType is VK_EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT and the fence is signaled at the time vkGetFenceFdKHR is called, pFd may return the value -1 instead of a valid file descriptor. So when above scenario happens, ANGLE will get a -1 fd from vkGetFenceFdKHR(), and then Angle will call SyncWaitFd() with the invalid fd, it will cause an ASSERT() crash.
