qcacld-3.0: Fix empty beacon report issue in 802.11k

Browse source 
While connected AP requires DUT to do radio
measurement for itself in passive scan mode,
DUT sends empty beacon report.

In passive scan, sta only listens beacons.
Connected AP beacon is offloaded to firmware, and
Firmware discards it except that special
IE exists in the beacon. Connected AP beacon will
not be sent to host. Hence, timer of connected BSS
is not updated in scan result lists
and cannot meet "scan timer > RRM_scan_timer".
Fix the issue by adding connected
BSS judging condition.

For cld3.2, csr_is_duplicate_bss_description is not
defined. So compare bssid only between scan results
and connected BSS.

Also fix some config issues in sme_rrm_issue_scan_req.
