Tomas Winkler 35c8bade33 mei: prevent unloading mei hw modules while the device is opened. ...

commit 154322f473 upstream.

chrdev_open() increases reference counter on cdev->owner. Instead of
assigning the owner to mei subsystem, the owner has to be set to the
underlaying HW module (mei_me or mei_txe), so once the device is opened
the HW module cannot be unloaded.
