wlcore: do not report noise level in get survey op
The get survey op expects the low level driver to report
the noise level for a a given channel.
The noise calculated in wlcore is (rssi-snr/2), but since
the snr reported by the FW is a derivative from the rssi
this calculation is useless, and should not be reported
to the user space.
Reporting incorrect noise, results in the wpa_supplicant
miscalculating the roaming candidate priority, thus causing
a situation where an AP with a lower rssi level would be
chosen over a better AP.
