Input: wacom - request tablet data for Bamboo Pens
Bamboo P&T need to use second form of usb_set_report() to
ask to report tablet data.
With previous addition of Bamboo Touch, BTN_TOOL_TRIPLETAP is now used
for both TABLETPC2FG and BAMBOO_PT types. So reduced check to
match type=TABLETPC2FG.
This change shows redundant check for !TABLETPC2FG in else statement.
