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") for reference.
