listener release error

[xuejiaolong]

Hi，
When i rmmod server it will call function unbind and function xio_context_destroy

function unbind will call xio_conn_close--xio_conn_release-->xio_rdma_close-->xio_rdma_post_close->kfree(hndl)

function xio_context_destroy will call xio_on_context_event->xio_on_context_close-->xio_rdma_context_shutdown, there will use trans_hndl , which is released but not null.

attachment is log pic.
