The driver reports NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR capability
to upper layer based on the service bit firmware reported. Driver
sets the spoofed flag in scan_ctrl_flag to firmware if upper layer
has enabled this feature in scan request.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
