    openmp: Fix up warnings on libgomp.info build
    
    When building libgomp documentation, I see
    makeinfo --split-size=5000000  -I ../../../libgomp/../gcc/doc/include -I ../../../libgomp -o libgomp.info ../../../libgomp/libgomp.texi
    ../../../libgomp/libgomp.texi:503: warning: node next `omp_get_default_device' in menu `omp_get_device_num' and in sectioning `omp_get_dynamic' differ
    ../../../libgomp/libgomp.texi:528: warning: node prev `omp_get_dynamic' in menu `omp_get_device_num' and in sectioning `omp_get_default_device' differ
    ../../../libgomp/libgomp.texi:560: warning: node next `omp_get_initial_device' in menu `omp_get_level' and in sectioning `omp_get_device_num' differ
    ../../../libgomp/libgomp.texi:587: warning: node next `omp_get_device_num' in menu `omp_get_dynamic' and in sectioning `omp_get_level' differ

    ../../../libgomp/libgomp.texi:615: warning: node prev `omp_get_level' in menu `omp_get_initial_device' and in sectioning `omp_get_device_num' differ
    warnings.  This patch fixes those.

            * libgomp.texi (omp_get_device_num): Move @node before omp_get_dynamic
            to avoid makeinfo warnings.
    
    (cherry picked from commit de7fa7063e99d29b6cc2024a90a3755a1001a154)
