    x86/vpmu: Fix build following vmfork addition
    
    GCC with IBT extensions complains:
    
      arch/x86/cpu/vpmu.c:351:15: error: conflicting types for 
'vpmu_save_force'; have 'void(void *)' with implied 'nocf_check' attribute
        351 | void cf_check vpmu_save_force(void *arg)
            |               ^~~~~~~~~~~~~~~

                       from arch/x86/cpu/vpmu.c:23:
      ./arch/x86/include/asm/vpmu.h:117:6: note: previous declaration of 
'vpmu_save_force' with type 'void(void *)'
        117 | void vpmu_save_force(void *arg);
            |      ^~~~~~~~~~~~~~~
    
    Adjust the declaraion.
