USB: vstusb.c: removal of driver for Vernier Software & Technology, Inc., devices and spectrometers

This patch removes the vstusb driver and support from the Linux tree. This driver provided support for Vernier Software & Technology devices and spectrometers (Ocean Optics). This driver is being replaced by a user space - libusb - implementation. Signed-off-by: Jim Collar <jim.collar@eqware.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

- *  If using multiple threads with this driver, the user should ensure that
