can: etas_es58x: remove useless calls to usb_fill_bulk_urb()
Aside of urb->transfer_buffer_length and urb->context which might
change in the TX path, all the other URB parameters remains constant
during runtime. So, there is no reasons to call usb_fill_bulk_urb()
each time before submitting an URB.
Make sure to initialize all the fields of the URB at allocation
time. For the TX branch, replace the call usb_fill_bulk_urb() by an
assignment of urb->context. urb->urb->transfer_buffer_length is
already set by the caller functions, no need to set it again. For the
RX branch, because all parameters are unchanged, simply remove the
call to usb_fill_bulk_urb().
