libwifi_hal: handle already-loaded kernel module
Sometimes the wifi HAL can get into a state where the module is already
loaded in a broken state and the wifi HAL isn't aware of this. When this
happens, try unloading and reloading the driver to unbreak wifi.
Before this failed with the following error:
E android.hardware.wifi@1.0-service: finit_module return: -1: File exists
