[urtw] Random wireless crash / kernel panic

[Adam Twardowski]

I do still have the kernel and the crash dump.  I'll try that fix tonight
to see how it goes.  Unfortunately, the kernel doesn't usually crash, more
likely the wifi stops working and I am forced to reboot the machine to get
it working again.
