The process of matching qpair to poll group is split into two distinct parts that occur on different threads. See spdk_nvmf_tgt_new_qpair(). This results in a race condition for TCP between spdk_sock_map_lookup() and spdk_sock_map_insert(), which are called in spdk_nvmf_get_optimal_poll_group() and spdk_nvmf_poll_group_add() respectively. Fixes #2113 This patch picks a hint from nvmf_tcp for next poll group, which is then passed down to spdk_sock_map_lookup(). When matching placement_id exists, but does not have a poll group assigned - the hint will be used.
