Subject: [PATCH] can: ctucanfd: Remove unnecessary print function dev_err()

The print function dev_err() is redundant because platform_get_irq()
already prints an error.

Eliminate the follow coccicheck warnings:

./drivers/net/can/ctucanfd/ctucanfd_platform.c:67:2-9: line 67 is
redundant because platform_get_irq() already prints an error.
