can: m_can: m_can_receive_skb(): add missing error handling to can_rx_offload_queue_sorted() call

In commit 1be37d3b0414 ("can: m_can: fix periph RX path: use
rx-offload to ensure skbs are sent from softirq context") the RX path
for peripherals (i.e. SPI based m_can controllers) was converted to
the rx-offload infrastructure. However, the error handling for
can_rx_offload_queue_sorted() was forgotten.
can_rx_offload_queue_sorted() will return with an error if the
internal queue is full.

This patch adds the missing error handling, by increasing the
rx_fifo_errors.
