Subject: [PATCH 1/7] can: rx-offload: continue on error

While can_rx_offload_offload_one will call mailbox_read to discard
the mailbox in case of an error, can_rx_offload_irq_offload_timestamp
bails out in the error case. Since it is typically called from a while
loop, all message will eventually be discarded. So lets continue on
error instead to discard them directly.
