svn commit: r206445 - head/sys/dev/iwn

Log:
  iwn4965_set_txpower() uses maxpwr from EEPROM to calculate the power to
  set, it make sense to actually initialize that array.  This fixes some
  issues with 4965 adapters where the TX power is crucial.
  
  This got lost somewhere while merging with the OpenBSD code.
