rtlwifi: rtl8192se: Fix incorrect signal strength for unassociated AP

commit b4ade797668e33b4e8353c2701ce01d7084dfafa upstream.

The routine that processes received frames was returning the RSSI value for the
signal strength; however, that value is available only for associated APs. As
a result, the strength was the absurd value of 10 dBm. As a result, scans
return incorrect values for the strength, which causes unwanted attempts to roam.

This patch fixes https://bugzilla.kernel.org/show_bug.cgi?id=63881.
