soc: fsl: dpio: Fix cleanup on IRQ registration failure

IRQ registration happens after dpaa2_io_create(), but its failure path
only releases the IRQ resources and the MC portal. The I/O object stays
allocated and published in the service list and per-CPU lookup table,
while devres unmaps its portal registers after probe fails.

Call dpaa2_io_down() on IRQ registration failure to remove the object
from those lookup structures and free it. Reorder the error labels so
that a failed dpaa2_io_create() still skips this cleanup.

Remove unregister_dpio_irq_handlers() from the probe error path, since
no IRQ handler or affinity hint has been installed when registration
fails.

This issue was identified during our ongoing static-analysis research
while reviewing kernel code.
