[PATCH net-next v2] netfilter: Fix incorrect tc_setup_type type for flowtable offload

[wenxu@ucloud.cn]

From: wenxu <wenxu@ucloud.cn>

Flowtable offload setup flow_offlod_block in TC_SETP_FT. The indr block
offload of flowtable also should setup in TC_SETUP_FT.
But flow_indr_block_call always sets the tc_set_up_type as TC_SETUP_BLOCK.
So function flow_indr_block_call should expose a parameters to set
the tc_setup_type for each offload subsystem.

Fixes: b5140a36da78 ("netfilter: flowtable: add indr block setup support")
