iommu: Remove duplicate ida_free in iommu_group_alloc
In the iommu_group_alloc, when the kobject_init_and_add
failed, the group->kobj is associate with iommu_group_ktype,
thus its release function iommu_group_release will be called
by the following kobject_put. The iommu_group_release calls
ida_free with the group->id, so we do not need to do it before
kobject_put.
