qcacld-3.0: Ignore uninitialized driver mode change

Browse source 
The driver mode can be dynamically controlled via the module parameter
"con_mode," which triggers the callback con_mode_handler(). However, if
the wlan module is loaded with a non-default con_mode, this callback
handler is invoked before module init (e.g. 'insmod wlan.ko
con_mode=5'). If con_mode_handler is invoked before module init, simply
return success, as no processing is needed.
