[GIT PULL] afs: Miscellaneous fixes

[David Howells]

Hi Linus,

Can you pull these miscellaneous fixes for afs please?

 (1) Fix a tracepoint that causes one of the tracing subsystem query files
     to crash if the module is loaded[1].

 (2) Fix afs_writepages() to take account of whether the storage rpc
     actually succeeded when updating the cyclic writeback counter[2].

 (3) Fix some error code propagation/handling[3].

 (4) Fix place where afs_writepages() was setting writeback_index to a file
     position rather than a page index[4].

Changes
=======

ver #2:
   - Fix an additional case of afs_writepages() setting writeback_index on
     error[4].
   - Fix afs_writepages() setting writeback_index to a file pos[4].

Thanks,
David
