Subject: [PATCH net] openvswitch: Remove conntrack Kconfig option.

There's no particular desire to have conntrack action support in Open
vSwitch as an independently configurable bit, rather just to ensure
there is not a hard dependency. This exposed option doesn't accurately
reflect the conntrack dependency when enabled, so simplify this by
removing the option. Compile the support if NF_CONNTRACK is enabled.

Fixes: 7f8a436eaa2c ("openvswitch: Add conntrack action")
