John Baldwin a8346a9865 A few cleanups to the FPU code on amd64:
- fpudna() always returned 1 since amd64 CPUs always have FPUs.  Change
  the function to return void and adjust the calling code in trap() to
  assume the return 1 case is the only case.
- Remove fpu_cleanstate_ready as it is always true when it is tested.
  Also, only initialize fpu_cleanstate when fpuinit() is called on the BSP.
