When setup tx queues, we will create a mempool for the 'gso_ctx'.
The mempool is not freed when closing tap device. If free the tap
device and create it with different name, it will create a new
mempool. This maybe cause an OOM.
The snprintf function return value is not checked and the mempool
name may be truncated. This patch also fix it.
