[PATCH nf 1/3] netfilter: nft_flow_offload: no need to flush entries on module removal

[Pablo Neira Ayuso <pablo@netfilter.org>]

nft_flow_offload module removal does not require to flush existing
flowtables, it is valid to remove this module while keeping flowtables
around.

This patch is a dependency for bugfix in patch 3/3. PATCH 2/3 moves
flowtable cleanup to the core, this patch saves us from exporting a
function that we would need to unexport just thereafter. So remove it
in first place to avoid unnecessary code churning.
