Input: usbtouchscreen - fix buffer overflow, make more egalax work
Fix a buffer overflow in mutli-packet handling code. The overflow can only happen with eGalax devices and is even there very unlikely (only non-report packet are affected any only when truncated after the first byte). Also changes the mutli-packet handling code not to drop unknown packets, but rather just drop one byte. This allows synchronizing on report packets in the data stream. It's required for some egalax devices to work at all. Also remove the pointless 'flags' member of the device struct and set the version number to 0.6, plus some minor cleanups.
