[PATCH 3/5] [media] pwc-if: fix build warning when !CONFIG_USB_PWC_INPUT_EVDEV

[Luis Henriques <luis.henriques@canonical.com>]

Label err_video_unreg in function usb_pwc_probe() is only used when
CONFIG_USB_PWC_INPUT_EVDEV is defined.

drivers/media/usb/pwc/pwc-if.c:1104:1: warning: label 'err_video_unreg' defined but not used [-Wunused-label]
