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.
