[PATCH 2/4] AFS: Part of afs_end_call() is identical to code elsewhere, so split it

[David Howells]

From: Nathaniel Wesley Filardo <nwf at cs.jhu.edu>

Split afs_end_call() into two pieces, one of which is identical to code in
afs_process_async_call().  Replace the latter with a call to the first part of
afs_end_call().
