add 10ms sleep after stop

Browse Source 
This seems to stop consumers that are doing quick back to back stop/start
(eg gqrx changing decode mode / filter bandwidth) from hanging the
device.

I now don't have any weird hangs on hackrf with gqrx/freebsd/libusb!

When things hang it isn't erroring out in any way; it just doesn't
start receive.  It doesn't look like a libusb issue; I'd have to get
some USB bus sniffing to see what's going on behind the scenes.
