From: Markus Schneider-Pargmann <msp@baylibre.com>

m_can_rx_peripheral() is a wrapper around m_can_rx_handler() that calls
m_can_disable_all_interrupts() on error. The same handling for the same
error path is done in m_can_isr() as well.

So remove m_can_rx_peripheral() and do the call from m_can_isr()
directly.
