util: use only /dev directory in open_dev()
Previously, open_dev() tried to open device in two ways - using /dev and /tmp directory. This method could be used by users which have no access to /tmp directory (e.g. udev) and dev_open() fails which may affect many processes. Remove try to open in /tmp directory.
