hostapd: donot process 2.4ghz probe requests

some of Google WiFi products firmware doesn't populate 2.4ghz probe
request info to user space which is required to decide station band
capability. As a work around, mark station as the dual band capable
if 5ghz probe request info of station are available.

BUG=b:139151531
TEST=1) Build for Google WiFi products
     2) Connect a station to Google WiFi and confirm from logs
