usb: mon: Change return type to vm_fault_t

Browse source 
Use new return type vm_fault_t for the 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.

vm_fault_t")
