qcacld-3.0: Conditionally enable WEXT support

Currently CONFIG_WLAN_WEXT_SUPPORT_ENABLE is unconditionally enabled
in many defconfigs, including the default defconfig, but this leads to
build failures when WEXT is not configured in the Kernel. So update
the defconfigs to enable CONFIG_WLAN_WEXT_SUPPORT_ENABLE only when
CONFIG_WIRELESS_EXT is enabled in the Kernel.
