Subject: [PATCH 11/14] RDS: Don't destroy the rdma id until after we're done using it

From: Santosh Shilimkar <ssantosh@...nel.org>

During connection resets, we are destroying the rdma id too soon. We can't
destroy it when it is still in use. So lets move rdma_destroy_id() after
we clear the rings.
