slimbus: qcom: Remove unnecessary print function dev_err()

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

Eliminate the follow coccicheck warning:
./drivers/slimbus/qcom-ctrl.c:514:2-9: line 514 is redundant because
platform_get_irq() already prints an error
