e715d44594 can: ctucanfd: ctucan_platform_probe(): 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.
