fs: kernfs: Adding new return type vm_fault_t
Use new return type vm_fault_t for page_mkwrite and
fault handler. 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.
Reference id -> 1c8f422059ae ("mm: change return type to
vm_fault_t")
