fuse: fix llseek bug
commit b48c6af2086ab2ba8a9c9b6ce9ecb34592ce500c upstream.
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.
