nl80211: Fix vendor command handling

In wiphy_info_handler(), vendor specific commands were
interpreted as QCA specific without checking for the OUI,
which caused incorrect setting of driver flags with
commands from other vendors. As a result, that could
prevent proper operation (e.g., inability to process CSA).

This patch ensures that QCA vendor specific commands are
checked against QCA OUI before related flags are set.
