[PATCH] [media] dib0700: Fix uninitialized protocol for NEC repeat codes

[Geert Uytterhoeven]

    drivers/media/usb/dvb-usb/dib0700_core.c: In function âdib0700_rc_urb_completionâ:
    drivers/media/usb/dvb-usb/dib0700_core.c:679: warning: âprotocolâ may be used uninitialized in this function

When receiving an NEC repeat code, protocol is indeed not initialized.
Set it to RC_TYPE_NECX to fix this.

Fixes: 2ceeca0499d74521 ("[media] rc: split nec protocol into its three variants")

Is RC_TYPE_NECX correct, or should it be RC_TYPE_NEC?
I used RC_TYPE_NECX based on the checks for {,not_}data and
{,not_}system for the other cases.
