From: William Kucharski rds_inc_init() initializes every field of the embedded rds_incoming except i_conn_path, and incomings are not zero-allocated (IB carves them out of a slab cache). The field therefore holds stale garbage for incs created by the non-multipath transports (rds_ib, loopback). Initialize it to NULL so that any future reader trips over a clean NULL pointer instead of a stale one, and so the two init helpers (rds_inc_init/rds_inc_path_init) leave the structure in an equivalent, fully-initialized state. Hardening only; no user-visible bug in the current code. This mirrors Oracle UEK commit "rds: rds_inc_init() should initialize the inc->i_conn_path field".
