mm/hmm: fix header file if/else/endif maze v2
The #if/#else/#endif for IS_ENABLED(CONFIG_HMM) were wrong. Because of this after multiple include there was multiple definition of both hmm_mm_init() and hmm_mm_destroy() leading to build failure if HMM was enabled (CONFIG_HMM set). Changed since v1: - Fix the maze when CONFIG_HMM is disabled not just when it is disabled. This fix bot build failure. - Improved commit message.
