iommu/ipmmu-vmsa: Remove ipmmu_utlb_disable()

The function is unused after commit 1b932ce ("iommu: Remove detach_dev callbacks") and so compilation fails with drivers/iommu/ipmmu-vmsa.c:305:13: error: ‘ipmmu_utlb_disable’ defined but not used [-Werror=unused-function] 305 | static void ipmmu_utlb_disable(struct ipmmu_vmsa_domain *domain, | ^~~~~~~~~~~~~~~~~~ Remove the function to fix the compile error.
