ARM: OMAP2+: omap_device: fix error return code in omap_device_copy_resources()

Fix to return error code -EINVAL from the irq_of_parse_and_map() error
handling case instead of 0, as done elsewhere in this function.

Fixes: d85a2d61432a ("ARM: OMAP2+: Populate legacy resources for dma
and smartreflex")
