fs: nfs: Adding new return type vm_fault_t

Browse Source 
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 1c8f422059 ("mm: change return type to
vm_fault_t") for reference.
