[ Upstream commit 7a1cd7238fde6ab367384a4a2998cba48330c398 ]
The information about tag size should not be printed without debug info set. Also print device major:minor in the error message to identify the device instance.
Also use rate limiting and debug level for info about used crypto API implementaton. This is important because during online reencryption the existing message saturates syslog (because we are moving hotzone across the whole device).
