char: agp: Change return type to vm_fault_t
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. Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t") was added in 4.17-rc1 to introduce the new typedef vm_fault_t. Currently we are making change to all drivers to return vm_fault_t for page fault handlers. As part of that char/agp driver is also getting changed to return vm_fault_t type from fault handler.
