afs: don't use PREPARE_WORK
PREPARE_[DELAYED_]WORK() are being phased out. They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. afs_call->async_work is multiplexed with multiple work functions. Introduce afs_async_workfn() which invokes afs_call->async_workfn and always use it as the work function and update the users to set the ->async_workfn field instead of overriding the work function using PREPARE_WORK(). It would probably be best to route this with other related updates through the workqueue tree. Compile tested.
