Subject: [PATCH 4.8 047/125] i40e: remove a stray unlock

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit be0cb0a66a1d426f7cd9b170c008725044ae147a upstream.

We shifted the locking around a bit but forgot to delete this unlock so
now it can unlock twice.

Fixes: cd3be169a5ff ('i40e: Move the mutex lock in i40e_client_unregister')
