can: kvaser_usb_leaf: do not report txerr and rxerr during bus-off

[ Upstream commit a57732084e06791d37ea1ea447cca46220737abd ]

During bus off, the error count is greater than 255 and can not fit in
a u8.

Fixes: 7259124e ("can: kvaser_usb: Split driver into kvaser_usb_core.c and kvaser_usb_leaf.c")
