qcacld-3.0: Open WLAN adapter in FTM mode after modules are started

According to the current code flow of con_mode_handler, the
WLAN modules are stopped, adapter is opened in FTM mode and then
the modules are started. Due to the INI/CFG value accces done as
part of opening the adapter, and since the modules are stopped
at this point, it results in a use after free scenario.

Modify code sequence of con_mode_handler to WLAN start modules
before opening the adapter in FTM mode.
