Subject: [PATCH 27/30] habanalabs: Add missing annotation for goya_hw_queues_lock()

Sparse reports a warning at goya_hw_queues_lock()
warning: context imbalance in goya_hw_queues_lock() - wrong count at exit
The root cause is a missing annotation at goya_hw_queues_lock()
Add the missing __acquires(&goya->hw_queues_lock) annotation
