iommu/mediatek: fix use-after-free on probe deferral

In the Linux kernel, the following vulnerability has been resolved:

iommu/mediatek: fix use-after-free on probe deferral

The driver is dropping the references taken to the larb devices during
probe after successful lookup as well as on errors. This can
potentially lead to a use-after-free in case a larb device has not yet
been bound to its driver so that the iommu driver probe defers.

Fix this by keeping the references as expected while the iommu driver is
bound.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
