FROMGIT: wifi: cfg80211: skip indicating signal for per-STA profile BSSs

Currently signal of the BSS entry generated from the per-STA profile
indicated as zero, but userspace may consider it as high signal
strength since 0 dBm is a valid RSSI value.

To avoid this don't report the signal to userspace when the BSS entry
created from a per-STA profile.
