From: Haiyang Zhang <[email-masked]>
Date: Fri, 19 Jul 2019 17:33:51 +0000

[ Upstream commit be4363bdf0ce9530f15aa0a03d1060304d116b15 ]

There is an extra rcu_read_unlock left in netvsc_recv_callback(),
after a previous patch that removes RCU from this function.
This patch removes the extra RCU unlock.

Fixes: 345ac08990b8 ("hv_netvsc: pass netvsc_device to receive callback")
