Android: Delay QCA roam+auth event until NL80211_CMD_ROAM is received
Information from both NL80211_CMD_ROAM and
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH events is required for
processing the roam events correctly, especially to get the newly
connected BSS details. Indicate the roam event to private libraries only
after NL80211_CMD_ROAM and QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH
events are received.
