Subject: [PATCH v2 net-next] net/rds: Remove unused function declarations

Commit 39de8281791c ("RDS: Main header file") declared but never implemented
rds_trans_init() and rds_trans_exit(), remove it.
Commit d37c9359056f ("RDS: Move loop-only function to loop.c") removed the
implementation rds_message_inc_free() but not the declaration.

Since commit 55b7ed0b582f ("RDS: Common RDMA transport code")
rds_rdma_conn_connect() is never implemented and used.
rds_tcp_map_seq() is never implemented and used since
commit 70041088e3b9 ("RDS: Add TCP transport to RDS").
