s390/ccwgroup: obtain extra reference for asynchronous processing Commit 0b60f9ead5d4816e7e3d6e28f4a0d22d4a1b2513 "s390: use device_remove_file_self() instead of device_schedule_callback()" changed ccwgroup to use an extra work queue instead of device_schedule_callback. This function obtained an extra device reference for its async work which is missing in the new implementation and results in a "freeing memory with a lock still held" BUG. Fix this by obtaining an extra reference for the async work.
