upstream: [media] dvbdev: add a dvb_detach() macro
The dvb_attach() was unbalanced, as there was no dvb_dettach. Ok, on current cases, the dettach is done by dvbdev, but that are some future corner cases where we may need to do this before registering the frontend. So, add a dvb_detach() and use it at dvb_frontend.c. Backports http://git.linuxtv.org/cgit.cgi/media_tree.git/commit/?id=4647f487083d Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
