mips_fulong2e: Don't register "cpu" VMState twice

Browse source 
We have the following simplified callgraph in mips_fulong2e_init():

  cpu_init() => cpu_mips_init()
    object_new()
      mips_cpu_initfn()
        cpu_exec_init()
          register_savevm(NULL, "cpu", cpu_index, CPU_SAVE_VERSION,
                          cpu_save, cpu_load, env)
  register_savevm(NULL, "cpu", 0, 3, cpu_save, cpu_load, env)

CPU_SAVE_VERSION is defined as 3 in target-mips/cpu.h.
fulong2e instantiates one CPU, so its cpu_index is 0.
Thus the two are fully identical.

Therefore just remove the second call in fulong2e.
