[PATCH 1/2] can: peak_usb: always ask for BERR reporting for PCAN-USB devices

[Stephane Grosjean <s.grosjean@peak-system.com>]

Since for the PCAN-USB, the management of the transition to the
ERROR_WARNING or ERROR_PASSIVE state is done according to the error
counters, these must be requested unconditionally.
