[media] em28xx: fix uninitialized variable warning 



Fix this daily build warning:

In file included from build/media_build/v4l/em28xx-core.c:35:0:
build/media_build/v4l/em28xx-core.c: In function 'em28xx_audio_setup':

  printk(KERN_INFO "%s: "fmt,\
  ^
build/media_build/v4l/em28xx-core.c:507:6: note: 'vid' was declared here
  u32 vid;
      ^

As far as I can tell 'vid' can not really be used uninitialized here, but the code
is sufficiently complex that apparently gcc can't figure that out.
