IB/iser: Make a couple of functions static
Make iser_conn_release() and iser_start_rdma_unaligned_sg() static, since they are only used in the .c file where they are defined. In addition to being a cleanup, this even shrinks the generated code by allowing the single call of iser_start_rdma_unaligned_sg() to be inlined into its callsite. On x86_64: add/remove: 0/1 grow/shrink: 1/0 up/down: 466/-533 (-67) function old new delta iser_reg_rdma_mem 1518 1984 +466 iser_start_rdma_unaligned_sg 533 - -533 Signed-off-by: Roland Dreier <rolandd@cisco.com>
