Subject: [PATCH] media: rkvdec: Propagate platform_get_irq() errors

platform_get_irq() returns a positive IRQ number on success and a
negative error code on failure. It no longer returns zero. The driver
currently returns -ENXIO for all failures, which loses useful errors
such as -EPROBE_DEFER.

Return the error from platform_get_irq() directly.
