If a discrete NIC is connected to a PCIe link hat isn't at least
Gen3 (8.0 GT/s), then we cannot sustain 320 MHz traffic, so remove
that from EHT capabilities in that case.

While at it, also move setting 320 MHz beamformee to the right
place in the code so it's not set while not supporting 320 MHz.

Is there not an advantage to allowing 320Mhz for longer distance connections
where signal is relatively weak, so over-all tput would easily fit in lesser
pcie bus?  Especially on 6E band where the US regdom allows more over-all power
when using wider bandwidths?

Thanks,
Ben
