fs/proc/vmcore.c: use new typedef 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 1c8f4220 ("mm: change return type to vm_fault_t") for reference.
