s390/mm,fault: remove VM_FAULT_PFAULT
Handling of VM_FAULT_PFAULT and VM_FAULT_BADCONTEXT is nearly identical; the only difference is within do_no_context() where however the fault_type (KERNEL_FAULT vs GMAP_FAULT) makes sure that both types will be handled differently. Therefore it is possible to get rid of VM_FAULT_PFAULT and use VM_FAULT_BADCONTEXT instead.
