There's no need to be fooling with XPT_BUSY now that all the threads
are gone.
The list_del_init() here could execute at the same time as the
svc_xprt_enqueue()'s list_add_tail(), with undefined results. We don't
really care at this point, but it might result in a spurious
list-corruption warning or something.
And svc_close() isn't adding any value; just call svc_delete_xprt()
directly.
