V4L/DVB (6095): ivtv: fix VIDIOC_G_ENC_INDEX flag handling
Due to a documentation bug (the type mask is 3 bits long, not 2) the wrong frame types were filled in: the B and P frame types were swapped. This bug also hid a second bug: when a capture is stopped a last entry is written into the pgm index buffer with internal type 0, denoting the end of the program. This entry wasn't ignored, instead it was accidentally returned to the caller as a P frame.
