[PATCH] kernel: relay: Change return type to vm_fault_t

[Souptick Joarder <jrdr.linux@gmail.com>]

Use new return type vm_fault_t for 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.
