crypto: algapi - Avoid spurious modprobe on LOADED
commit beeb460c upstream. Currently after any algorithm is registered and tested, there's an unnecessary request_module("cryptomgr") even if it's already loaded. Also, CRYPTO_MSG_ALG_LOADED is sent twice, and thus if the algorithm is "crct10dif", lib/crc-t10dif.c replaces the tfm twice rather than once. This occurs because CRYPTO_MSG_ALG_LOADED is sent using crypto_probing_notify(), which tries to load "cryptomgr" if the notification is not handled (NOTIFY_DONE). This doesn't make sense because "cryptomgr" doesn't handle this notification. Fix this by using crypto_notify() instead of crypto_probing_notify().
