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

[Jiapeng Chong <jiapeng.chong@linux.alibaba.com>]

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

./drivers/net/can/bxcan.c:970:2-9: line 970 is redundant because platform_get_irq() already prints an error.
./drivers/net/can/bxcan.c:964:2-9: line 964 is redundant because platform_get_irq() already prints an error.
./drivers/net/can/bxcan.c:958:2-9: line 958 is redundant because platform_get_irq() already prints an error.
