fuse: don't advise readdirplus for negative lookup
If the FUSE_READDIRPLUS_AUTO feature is enabled, then lookups on a directory before/during readdir are used as an indication that READDIRPLUS should be used instead of READDIR. However if the lookup turns out to be negative, then selecting READDIRPLUS makes no sense. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
