Subject: [PATCH] power: supply: cw2015: Free allocated workqueue

Use devm interface so allocated workqueue will be freed during device removal and error paths, thus fixing a memory leak.

Change is not equivalent in the workqueue itself: use non-legacy API which does not set (__WQ_LEGACY | WQ_MEM_RECLAIM). The workqueue is used to read updated data from the battery, thus there is no point to run it for memory reclaim.
