gpu: drm: qxl: Adding new typedef 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.

Reference id -> 1c8f4220 ("mm: change return type to
vm_fault_t")
