[PATCH] airo.c - don't clear FLAG_RADIO_DOWN on resume

[Michal Schmidt <xschmi00@xxxxxxxxxxxxxxxxxx>]

Hello,

According to comments in airo.c the flag FLAG_RADIO_DOWN means:
  Radio disabled via "ifconfig ethX down".
airo_pci_resume clears this flag.
This causes a little problem I can reproduce on my IBM ThinkPad R40 with 
Cisco Aironet mini-PCI card (MPI350) with these steps:
1) ifup eth0 => card works OK, radio status LED indicator is on
2) ifdown eth0 => LED turns off
3) hibernate using swsuspend
4) resume from swsuspend
Result: interface eth0 is down, but the LED indicates that radio is on.
Expected result: interface eth0 is down, so the radio should be off.

I think that airo_pci_resume shouldn't mess with FLAG_RADIO_DOWN. I have 
removed the line and now everything works as expected. One-line patch 
attached.
