  The core sets the usb_interface to NULL in [1]. Also setting it to
NULL in usb_driver::disconnect() is useless.

Remove the calls to usb_set_intfdata(intf, NULL) in the disconnect
functions of all drivers under drivers/net/can/usb, namely etas_es58x
and peak_usb.

[1] function usb_unbind_interface() from drivers/usb/core/driver.c
