[PATCH 6/6] rt2x00: Fix GCC warning because aifs is now unsigned

[Ivo van Doorn <ivdoorn@gmail.com>]

The aifs type has recently been changed to unsigned,
this triggered the following gcc warning:

  CC [M]  drivers/net/wireless/rt2x00/rt2x00mac.o
  drivers/net/wireless/rt2x00/rt2x00mac.c: In function 'rt2x00mac_conf_tx':
  drivers/net/wireless/rt2x00/rt2x00mac.c:557: warning: comparison is always true due to limited range of data type
