qcacld-3.0: Clean up station stats for get station vendor cmd

User requests station stats using QCA_NL80211_VENDOR_SUBCMD_GET_STA_INFO
command. Presently host request peer stats from FW when user request
station stats for STA mode. FW doesn't support peer stats for STA mode.
Hence clean up the code for get station vendor command for STA mode.
