    gNFS: gNFS drc cache failed to detecte duplicates.
    
    After the drc cache get full, message "DRC failed to detect duplicates" keep
    printed in the log.
    The root cause is drc_compare_reqs use the wrong compare type. This function
    should use type drc_cache_op_t as its input type. Since all rbtree related code
    (except function rpcsvc_drc_lookup) in drc cache pass drc_cache_op_t as compare
    type. Only rpcsvc_drc_lookup use type rpcsvc_request_t. It has been modified
    too.
