If module A depends on module B and module B has not yet finished its
init() the module loader may print a warning about an unknown symbol.
This happens if module B is still in state MODULE_STATE_COMING,
as module A runs into resolve_symbol() for a symbol from module B.
resolve_symbol() return 0 in that case and causes the warning.
