Subject: [PATCH] iommu/mediatek: Fix error code in probe()

This error path is supposed to return -EINVAL. It used to return
directly but we added some clean up and accidentally removed the
error code. Also I fixed a typo in the error message.

Fixes: c0b57581b73b ("iommu/mediatek: Add power-domain operation")
