arm64/mm: Refactor {pgd, pud, pmd, pte}_ERROR()
The function __{pgd, pud, pmd, pte}_error() are introduced so that they can be called by {pgd, pud, pmd, pte}_ERROR(). However, some of the functions could never be called when the corresponding page table level isn't enabled. For example, __{pud, pmd}_error() are unused when PUD and PMD are folded to PGD. This removes __{pgd, pud, pmd, pte}_error() and call pr_err() from {pgd, pud, pmd, pte}_ERROR() directly, similar to what x86/powerpc are doing. With this, the code looks a bit simplified either.
