Tyler found build issues with MSVC and the thash gfni stubs. The problem would be link errors from missing symbols. The purpose of the original commit was to allow local definition of RTE_LOGTYPE_HASH. Put the thash gfni back as inlines, but require that the header only be included inside rte_thash.h so that the log macros are defined.
