ARM: 9161/1: 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
