Don't uninstall flow tables in setup_dvr_flows_on_integ_br
This is a revise for I7b24a159962af7b58c096a1b2766e2169e9f8aed
Br-int's flow tables are already uninstalled in setup_integration_br.
And setup_integration_br will install some default flows. If we still
uninstall flow tables of br-int in setup_dvr_flows_on_integ_br, these
default flow tables will be missing.

But, when 'drop_flows_on_start' is configured true, some requisite flows will
be missing.
