[GIT PULL] afs: Miscellany for 5.3

[David Howells]

Hi Linus,

Here's a set of minor changes for AFS for the next merge window:

 (1) Remove an unnecessary check in afs_unlink().

 (2) Add a tracepoint for tracking callback management.

 (3) Add a tracepoint for afs_server object usage.

 (4) Use struct_size().

 (5) Add mappings for AFS UAE abort codes to Linux error codes, using
     symbolic names rather than hex numbers in the .c file.
