media: rc: unlock on error in show_protocols()
commit 30ebc5e44d057a1619ad63fe32c8c1670c37c4b8 upstream. We recently introduced a new return -ENODEV in this function but we need to unlock before returning. [mchehab@redhat.com: found two patches with the same fix. Merged SOB's/acks into one patch] Acked-by: Herton R.
