can: m_can: m_can_handle_lec_err(): fix {rx,tx}_errors statistics

[ Upstream commit 988d4222 ]

The m_can_handle_lec_err() function was incorrectly incrementing only the
receive error counter, even in cases of bit or acknowledgment errors that
occur during transmission.

Fix the issue by incrementing the appropriate counter based on the
type of error.
