[PATCH] ARM: mm: mark private VM_FAULT_X defines as vm_fault_t

This fixes several sparse warnings for fault.c:

arch/arm/mm/fault.c:210:24: sparse:     expected restricted vm_fault_t
arch/arm/mm/fault.c:210:24: sparse:     got int
...
arch/arm/mm/fault.c:345:24: sparse: sparse: restricted vm_fault_t degrades to integer

Fixes: caed89dab0ca ("ARM: 9128/1: mm: Refactor the __do_page_fault()")
