ath10k: Fix unwanted probe requests sent during p2p scan

During p2p find unwanted probe requests with broadcast SSID is
sent along with the probe requests with p2p wildcard SSID.

The addition of survey report flag in scan flags initiates an
active scan along with the p2p scan, due to which we see probe
requests with broadcast SSID along with the probe requests having
p2p wildcard SSID.

Fix the flags sent during scan command for p2p scan.
