We currently only create one queue per queue family on the device. The
device can be shared between multiple zink_screens, so having one lock
per screen can still lead to multiple locks per queue. Fix this by
allocating queue_lock along with the device.
This fixes an issue that was causing crashes with nvk+zink and
QtWebEngine with QTWEBENGINE_FORCE_USE_GBM=1 This can be reproduced by
resizing the window in either:
* anki - https://apps.ankiweb.net/ or
* Qt's simplebrowser example
https://doc.qt.io/qt-6/qtwebengine-webenginewidgets-simplebrowser-example.html
which would then cause this dmesg error:
nouveau 0000:01:00.0: anki[92007]: Failed to find syncobj (-> in): handle=40
along with a context loss.
With VK_LOADER_LAYERS_ENABLE=VK_LAYER_KHRONOS_validation we would additionally
get warnings like:
Validation Error: [ UNASSIGNED-Threading-MultipleThreads-Write ] | MessageID = 0xa05b236e
vkQueueSubmit(): THREADING ERROR : object of type VkQueue is simultaneously used in current thread 139824449189568 and thread 139823901816512
