iommu: Don't take group reference in iommu_alloc_default_domain()
The iommu_alloc_default_domain() function takes a reference to an IOMMU
group without releasing it. This causes the group to never be released,
with undefined side effects.
The function has only one call-site, which takes a group reference on
its own, so to fix this leak, do not take another reference in
iommu_alloc_default_domain() and pass the group as a function parameter
instead.
Fixes: 6e1aa2049154 ("iommu: Move default domain allocation to iommu_probe_device()")
