Mauro Carvalho Chehab a9cb97c3e6 media: dvb_frontend: be sure to init dvb_frontend_handle_ioctl() return code 
As smatch warned:
	drivers/media/dvb-core/dvb_frontend.c:2468 dvb_frontend_handle_ioctl() error: uninitialized symbol 'err'.

The ioctl handler actually got a regression here: before changeset
d73dcf0cdb ("media: dvb_frontend: cleanup ioctl handling logic"),
the code used to return -EOPNOTSUPP if an ioctl handler was not
implemented on a driver. After the change, it may return a random
value.

Fixes: d73dcf0cdb ("media: dvb_frontend: cleanup ioctl handling logic")
