kmodloader: lift restriction on module alias info kmodloader has a restriction of storing only 32 aliases for a given module; as modules can have easily more than 32 aliases let's remove the restriction by using a dynamic allocation mechanism when retrieving the aliases. While at it also check the get_module_info return value setting an error code in case NULL is returned. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
