[PATCH] async_tx: fix kernel-doc notation warnings

[Randy Dunlap]

Fix W=1 kernel-doc warnings by adding "struct" keyword:

crypto/async_tx/async_tx.c:136: warning: cannot understand function prototype: 'enum submit_disposition '
crypto/async_tx/async_pq.c:18: warning: cannot understand function prototype: 'struct page *pq_scribble_page; '

Also fix 2 function parameter descriptions.
