The hwsp_gtt object is used for sub-allocation and could therefore be shared by many contexts causing unnecessary contention during concurrent context pinning. However since we're currently locking it only for pinning, it remains resident until we unpin it, and therefore it's safe to drop the lock early, allowing for concurrent thread access.
