Subject: [net-next 2/7] can: rx-offload: can_rx_offload_offload_one(): avoid double unlikely() notation when using IS_ERR()

From: Antonio Quartulli <a@...table.cc>

The definition of IS_ERR() already applies the unlikely() notation when
checking the error status of the passed pointer. For this reason there is no
need to have the same notation outside of IS_ERR() itself.

Clean up code by removing redundant notation.
