can: ifi_canfd: ifi_canfd_handle_lec_err(): fix {rx,tx}_errors statistics

[ Upstream commit bb03d568bb21b4afe7935d1943bcf68ddea3ea45 ]

The ifi_canfd_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.
