AFS: AFS fixups
Make some miscellaneous changes to the AFS filesystem:
(1) Assert RCU barriers on module exit to make sure RCU has finished with
callbacks in this module.
(2) Correctly handle the AFS server returning a zero-length read.
(3) Split out data zapping calls into one function (afs_zap_data).
(4) Rename some afs_file_*() functions to afs_*() where they apply to
non-regular files too.
(5) Be consistent about the presentation of volume ID:vnode ID in debugging
output.
