avrftdi: apply patch by rliebscher. 

Use pin_checklist[] of size N_PINS instead N_PINS - 1, to avoid future
problems. Also remove pins_check from set_pin; instead use mask[0] == 0
to check wether to do something or not.

avrftdi_private.h: Change size of pin_checklist[] to N_PINS.
avrftdi.c: Adapt code to new size of pin_checklist. Remove pins_check
from set_pin.

* avrftdi_private.h: Change size of pin_checklist to N_PINS (from N_PINS-1)
* avrftdi.c: Adapt code to new size of pin_checklist. Remove pins_check()
from set_pin().
