ath5k_pci: gain calibration timeout / unable to reset hardware -11

[Soeren Sonnenburg]

Hi,

I was using the ath5k_pci driver on a macbook pro 1,1 and it is working
for some time but then suddenly messages like the ones below appear and
I have to *turn off* the machine to get it back working (even booting to
osx is not sufficient - osx won't have network when things go wrong as
they do after a couple of hours). Note that this happens with both
2.6.27 and .28.

(things were working at first and then not and then the symptom occured)
