My understanding from reading the code is that "last_scanned_cnt + 1"
is a randomly chosen invalid value. Just saying:
sel_bssi_idx = last_scanned_cnt;
would also work because it's also invalid and slightly shorter to type.
But I suggest that you go with something like UINT_MAX because that's
more clearly invalid.

Combine these with an ||.
if (!sme->bssid) {
if (sel_bssi_idx == UINT_MAX ||
last_scanned_shadow[i].rssi >
last_scanned_shadow[sel_bssi_idx].rssi)
sel_bssi_idx = i;
In a separate patch, you can reverse the if statement at the start of
the loop:
if (sme->ssid_len != last_scanned_shadow[i].ssid_len ||
memcmp(last_scanned_shadow[i].ssid, sme->ssid,
sme->ssid_len) != 0)
continue;
That way you can pull these lines in a tab.

Add a space before the curly brace.
