Vasant Hegde a807e4f4f6 iommu/amd: Fix error path in amd_iommu_probe_device() 
[ Upstream commit 3222b6de51 ]

Currently, the error path of amd_iommu_probe_device() unconditionally
references dev_data, which may not be initialized if an early failure
occurs (like iommu_init_device() fails).

Move the out_err label to ensure the function exits immediately on
failure without accessing potentially uninitialized dev_data.

Fixes: 19e5cc156c ("iommu/amd: Enable support for up to 2K interrupts per function")
