can: gs_usb: gs_can_open(): initialize time counter before starting device
On busy networks the CAN controller might receive CAN frames directly
after starting it but before the timecounter is setup. This will lead
to NULL pointer deref while converting the converting the CAN frame's
timestamp with the timecounter.
Close the race window by setting up the timecounter before starting
the CAN controller.
