Subject: [PATCH v2] async_tx: fix kernel-doc notation warnings

Fix kernel-doc warnings by adding "struct" keyword or "enum" keyword.
Also fix 2 function parameter descriptions.
Change some functions and structs from kernel-doc /** notation
to regular /* comment notation.

Sure will do. Thanks for fixing this up, I think these might be
the last warnings under the crypto directory :)
