RDKB-35809 correcting prints in CosaDmlWiFiSsidGetSinfo

Impacted Platforms:
All RDKB Boxes

Reason for change:
Null BSSID printed for vaps that are down
So added a condition to check NULL and then print BSSID
If vap is down, we will not BSSID but just log a message

Test Procedure:

210526-04:30:46.341743 [mod=WIFI, lvl=INFO] [tid=4963] CosaDmlWiFiSsidGetSinfo : wlanIndex[2] BSSID [F2:AA:A0:81:7A:08]

210526-04:30:47.394064 [mod=WIFI, lvl=WARN] [tid=4963] CosaDmlWiFiSsidGetSinfo : HAL function wifi_getBaseBSSID returns bssid as NULL string for wlanIndex[8]

Risks: Low
