Input: wacom - ignore unwanted bamboo packets
Bamboo's Pen and Touch packets always start with a value of 0x02 in first byte. In 3rd gen Bamboo's, the hw is now periodically sending some additional packets with unrelated data and uses a value other than 0x02 to inform driver this. Ignore those packets now. This was reported by users as bad behavior in Gimp. The invalid packets being processed made the stylus report out of proximity for the 1 packet and this triggered some secondary bug which caused Gimp to stop drawing until user really took pen out of proximity of tablet.
