can: mcp251x: Replace create_freezable_workqueue with alloc_workqueue
Replace scheduled to be removed create_freezable_workqueue with alloc_workqueue. priv->wq should be explicitly set as freezable to ensure it is frozen in the suspend sequence and work items are drained so that no new work item starts execution until thawed. Thus, use of WQ_FREEZABLE flag here is required. WQ_MEM_RECLAIM flag has been set here to ensure forward progress regardless of memory pressure. The order of execution is not important so set @max_active as 0.
