[PATCH] Input: Do not add SYN_REPORT in between a single packet data

[Aniroop Mathur]

As mentioned in documentation, SYN_REPORT should be used to separate two packets
and should not be inserted in between a single packet as otherwise with multiple
SYN_REPORT in a single packet, input reader would not be able to know when the
packet ended really.

Documentation snippet:
* SYN_REPORT:
  - Used to synchronize and separate events into packets of input data changes
    occurring at the same moment in time. For example, motion of a mouse may set
    the REL_X and REL_Y values for one motion, then emit a SYN_REPORT. The next
    motion will emit more REL_X and REL_Y values and send another SYN_REPORT.
