Karsten Keil 4b921eda53 mISDN: Fix wrong usage of flush_work_sync while holding locks ...

It is a bad idea to hold a spinlock and call flush_work_sync.
Move the workqueue cleanup outside the spinlock and use cancel_work_sync,
on closing the channel this seems to be the more correct function.
Remove the never used and constant return value of mISDN_freebchannel.
