mm: change return type to vm_fault_t
Use new return type vm_fault_t for fault handler in struct
vm_operations_struct. For now, this is just documenting that the
function returns a VM_FAULT value rather than an errno. Once all
instances are converted, vm_fault_t will become a distinct type.
See commit 1c8f422059ae ("mm: change return type to vm_fault_t")
