Miklos Szeredi ef2d68ef9a ovl: fix uninitialized pointer read in ovl_lookup_real_one() ...

[ Upstream commit 580c610429b3994e8db24418927747cf28443cde ]

One error path can result in release_dentry_name_snapshot() being called
before "name" was initialized by take_dentry_name_snapshot().

Fix by moving the release_dentry_name_snapshot() to immediately after the
only use.
