Input: wacom - cleanup feature report for bamboos 

Only the stylus interface on Bamboo's has a feature report that can
be used to set to wacom mode.  The touch interface only has 1 report mode
and will return errors for those get/sets requests.

The get request was always erroring out because it was not marked as
an input request. Only down side of error was needlessly resending the
set request 5 times.
