    libnl-tiny: Remove GENL_ID_GENERATE
    
    This constant was always defined to 0, and recently got removed in
    upstream commit a07ea4d9941af5a0c6f0be2a71b51ac9c083c5e5 ("genetlink: no
    longer support using static family IDs")
    
    Fixes libnl-tiny builds with latest upstream kernels.
    
    Fixes: d723f2573af3 ("libnl-tiny: remove include/linux overrides to fix various build issues")
    Signed-off-by: Florian Fainelli <f.fainelli at gmail.com>
