can: gs_usb: convert from usb_control_msg() to usb_control_msg_{send,recv}()

Convert the driver to use usb_control_msg_{send,recv}() instead of
usb_control_msg(). These functions allow the data to be placed on the
stack. This makes the driver a lot easier as we don't have to deal
with dynamically allocated memory.
