    openmp, c++: Fix up OpenMP/OpenACC handling in C++ modules [PR119102]: Update 'module_state' comment for 'SE_BITS' change
    
    Minor fix-up for commit ddeb70548c81f5dba91f281290584698897151d8
    "openmp, c++: Fix up OpenMP/OpenACC handling in C++ modules [PR119102]", which
    did:
    
         enum streamed_extensions {
        -  SE_OPENMP = 1 << 0,
        -  SE_BITS = 1
        +  SE_OPENMP_SIMD = 1 << 0,
        +  SE_OPENMP = 1 << 1,
        +  SE_OPENACC = 1 << 2,
        +  SE_BITS = 3
         };
    
    ..., but didn't update the documentary use of 'SE_BITS' in 'module_state'.
