[PATCH net] net/mlx5e: Fix unnecessary flow_block_cb_is_busy call

[wenxu]

From: wenxu <we...@ucloud.cn>

When call flow_block_cb_is_busy. The indr_priv is guaranteed to
NULL ptr. So there is no need to call flow_bock_cb_is_busy.

Fixes: 0d4fd02e7199 ("net: flow_offload: add flow_block_cb_is_busy() and use 
it")
