ipvs: avoid netns exit crash on ip_vs_conn_drop_conntrack 

commit 2627b7e15c5064ddd5e578e4efd948d48d531a3f upstream.

commit 8f4e0a1868 ("IPVS netns exit causes crash in conntrack")
added second ip_vs_conn_drop_conntrack call instead of just adding
the needed check. As result, the first call still can cause
crash on netns exit. Remove it.
