fuse: always revalidate rename target dentry
commit ccc031e26afe60d2a5a3d93dabd9c978210825fb upstream.
The previous commit df8629af2934 ("fuse: always revalidate if exclusive
create") ensures that the dentries are revalidated on O_EXCL creates. This
commit complements it by also performing revalidation for rename target
dentries. Otherwise, a rename target file that only exists in kernel
dentry cache but not in the filesystem will result in EEXIST if
RENAME_NOREPLACE flag is used.
