USB: disable USB_MULTITHREAD_PROBE

Browse source 
Disable the USB_MULTITHREAD_PROBE option because it causes crashes on
people's machines and they never remember to actually read the config
help files.

No one likes this, everyone hates it, I'm going to go eat worms...

The full logic will be ripped out later.

Say Y here if you want the USB core to spawn a new thread for
every USB device that is probed. This can cause a small speedup
in boot times on systems with a lot of different USB devices.
This option should be safe to enable, but if any odd probing
problems are found, please disable it, or dynamically turn it
off in the /sys/module/usbcore/parameters/multithread_probe
file
When in doubt, say N.
