Lin Ma 88a6f8a72d media: dvbdev: adopts refcnt to avoid UAF
[ Upstream commit 0fc044b2b5 ]

dvb_unregister_device() is known that prone to use-after-free.
That is, the cleanup from dvb_unregister_device() releases the dvb_device
even if there are pointers stored in file->private_data still refer to it.

This patch adds a reference counter into struct dvb_device and delays its
deallocation until no pointer refers to the object.
