mac80211: rt2x00: fix LED polarity patch 

The patch causes compiler warning ...

  <...>/drivers/net/wireless/rt2x00/rt2800lib.c: In function 'rt2800_init_eeprom':
  <...>/drivers/net/wireless/rt2x00/rt2800lib.c:5971:2: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]

... and runtime errors on PCI/USB devices:
