ovs-lib.in: Remove unnecessary conntrack flush

We introduced flush-conntrack in force-reload-kmod script by commit
8bea39b186ca ("datapath: Prevent panic") to prevent kernel panic.
It turns out that the kernel panic is actually triggered by the
IPv4 secret timer, and it is fixed by commit
121905984724 ("compat: Initialize IPv4 reassembly secret timer").

This commit removes the unnecessary conntrack flush in the script.
