    redhat: rh_flags: make the !CONFIG_RHEL_DIFFERENCES stubs inline
    
    The stubs are declared "static void", not "static inline void", so every
    translation unit that includes rh_flags.h without calling them gets two
    unused functions.  That breaks the build of any kernel that has
    CONFIG_RHEL_DIFFERENCES off and CONFIG_WERROR on - x86_64 defconfig,
    which we now want to keep building, is one of them:
    
      include/linux/rh_flags.h:32:13: error: 'rh_add_flag' defined but not
                                      used [-Werror=unused-function]
      include/linux/rh_flags.h:31:13: error: 'rh_print_flags' defined but not
                                      used [-Werror=unused-function]
    
    Fixes: 5e75024bc506 ("redhat: rh_flags: declare proper static methods when !CONFIG_RHEL_DIFFERENCES")
    Feature: fix rh/flags
