rt2800: validate step value for temperature compensation

commit bf7e1abe434ba9e22e8dc04a4cba4ab504b788b8 upstream.

Some hardware has correct (!= 0xff) value of tssi_bounds[4] in the
EEPROM, but step is equal to 0xff. This results on ridiculous delta
calculations and completely broke TX power settings.
