build: fix the build error with invalid preprocessing token

    We encounter the following error during build

    In file included from /nfs-ganesha/src/monitoring/include/prometheus_exposer.h:35,
                     from /nfs-ganesha/src/monitoring/prometheus_exposer.cc:37:
    /nfs-ganesha/src/libntirpc/src/monitoring/include/monitoring.h:162:22: error: pasting "NOT_USED_" and "*" does not give a valid preprocessing token

    The `NOT_USED_##arg` is invalidate with the pointer preprocessing.
    We should move the pointer out of the macro likes libntirpc does.
