-module: fix symbol waiting when module fails before init
-
-We use resolve_symbol_wait(), which blocks if the module containing
-the symbol is still loading.  However:
-
-1) The module_wq we use is only woken after calling the modules' init
-   function, but there are other failure paths after the module is
-   placed in the linked list where we need to do the same thing.
-
-2) wake_up() only wakes one waiter, and our waitqueue is shared by all
-   modules, so we need to wake them all.
-
-3) wake_up_all() doesn't imply a memory barrier: I feel happier calling
-   it after we've grabbed and dropped the module_mutex, not just after
-   the state assignment.
