s390/tlb: Add missing TLB range adjustment

While converting to generic mmu_gather with commit 9de7d833e370
("s390/tlb: Convert to generic mmu_gather") __tlb_adjust_range()
is called from pte|pmd|p4d_free_tlb(), but not for pud_free_tlb().

__tlb_adjust_range() adjusts the span of TLB range to be flushed,
but s390 does not make use of it. Thus, this change is only for
consistency.
