[PATCH] wl12xx: Correctly set up protection if non-GF STAs are present

I don't know wl12xx as all and I don't have such a device. This is based on the
assumption that setting acx->gf_protection to 1 enables protection for GF
transmissions. So, this is only compile tested.

It just popped up while discussing HT operation mode handling in hostapd.

Please review.
 
Thanks,
Helmut

This is good, thanks Helmut! We had some problems with earlier versions
of our firmware where this was apparently not implemented, that's why we
were setting it always to 0.

I added a description to your commit, hope you don't mind.

Applied!
