[Devel] [PATCH vz10 28/32] redhat: rh_flags: make the !CONFIG_RHEL_DIFFERENCES stubs inline

[Konstantin Khorenko <khorenko@virtuozzo.com>]

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
