[PATCH 4.9 109/177] qed: Unlock on error in qed_vf_pf_acquire()

[Greg Kroah-Hartman]

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

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

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>


[ Upstream commit 66117a9d9a8ca948680d6554769ef9e88f936954 ]

My static checker complains that we're holding a mutex on this error
path.  Let's goto exit instead of returning directly.

Fixes: b0bccb69eba3 ("qed: Change locking scheme for VF channel")
