[GIT PULL] afs: Minor cleanups and a minor bugfix

[David Howells]

Hi Linus,

Can you pull these AFS patches please?  They are:

 (1) Minor fix to make some debugging statements display information from
     the correct iov_iter.

 (2,3) Rename some members and variables to make things more obvious or
     consistent.

 (4) Provide a helper to wrap increments of the usage count on the afs_read
     struct.

 (5) Use scnprintf() to print into a stack buffer rather than sprintf().

 (6,7) Remove some set but unused variables.

There should be no functional changes from (2) - (7).

Thanks,
David
