fs: do not compare against ->llseek
Now vfs_llseek() can simply check for FMODE_LSEEK; if it's set, we know that ->llseek() won't be NULL and if it's not we should just fail with -ESPIPE. A couple of other places where we used to check for special values of ->llseek() (somewhat inconsistently) switched to checking FMODE_LSEEK. Signed-off-by: Jason A.
