Subject: [PATCH v3 06/26] media: stm32-dcmipp: Remove redundant printk

platform_get_irq() already prints an error message.

Also platform_get_irq() can never return 0, so lets fix the condition
now that we are at it.

Found by cocci:
drivers/media/platform/st/stm32/stm32-dcmipp/dcmipp-core.c:444:3-10: line 444 is redundant because platform_get_irq() already prints an error
