emulate_sys_reg() returns 1 unconditionally, even though a a system register access can fail. Furthermore, kvm_handle_sys_reg() writes to Rt for every register read, regardless of if it actually succeeded. Though this pattern is safe (as params.regval is initialized with the current value of Rt) it is a bit ugly. Indicate failure if the register access could not be emulated and only write to Rt on success.
