NFSv4: Fix a dentry leak on alias use

Browse source

[ Upstream commit d9dfd8d741 ]

In the case where d_add_unique() finds an appropriate alias to use it will
have already incremented the reference count.  An additional dget() to swap
the open context's dentry is unnecessary and will leak a reference.
