[media] gspca: reset image_len to 0 on LAST_PACKET when discarding frame

Browse Source 
Reset image and image_len to NULL/0 on LAST_PACKET when we're in discard
frame mode, just like we do when not discarding the current frame.

The new se401 driver uses image_len for SOF/EOF detection and thus depends on
this.
