s390/mm: use generic mm_hooks
With git commit 3446c13b268af86391d06611327006b059b8bab1
"s390/mm: four page table levels vs. fork"
s390 dropped its architecture specific version of arch_dup_mmap.
Now all functions defined by include/asm-generic/mm_hooks.h are
identical to the s390 versions. Use the generic header.
