fuse: fix llseek bug
The test in fuse_file_llseek() "not SEEK_CUR or not SEEK_SET" always evaluates to true. This was introduced in 3.1 by commit 06222e49 (fs: handle SEEK_HOLE/SEEK_DATA properly in all fs's that define their own llseek) and changed the behavior of SEEK_CUR and SEEK_SET to always retrieve the file attributes. This is a performance regression. Fix the test so that it makes sense.
