afs: remove dead ICL (fstrace) code
The ICL code (afs/afs_icl.c) which supports fstrace includes a number of functions that have been dead code since the original IBM code import. Some of these seem to have been intended to support fine-grained event tracing, but the implementation was never completed. Remove the dead code. No functional change is incurred by this commit.
