solo6010-dkms: load instantly

[andrey-utkin]

Currently DKMS package does nothing to unload mainline driver and load itself. By this reason software doesn't work properly until machine is rebooted.
Looks rmmod & modprobe commands should be added to Makefile "install" target or like that.
The only concern is pulseaudio which tends to capture to death all available audio devices (and solo driver provides them). So pulseaudio processes must be killed reliably to accomplish this. And bc-server process. Everything.
If module is still used (rmmod failure would show this), and we cannot do nothing, a warning must be shown to user, urging them to reboot the host.
