If a directory has a block with only ".__afsXXXX" files in it (from
uncompleted silly-rename), these .__afsXXXX files are skipped but without
advancing the file position in the dir_context. This leads to
afs_dir_iterate() repeating the block again and again.
Fix this by making the code that skips the .__afsXXXX file also manually
advance the file position.
The symptoms are a soft lookup:
