svcrdma: Initialize the context free list for listeners

Move the initialization of the sc_ctxt_free list to the client/listener generic bit of the init logic. This is necessary to avoid a bug check when shutting down a listening endpoint when list debug is enabled. This bug was introduced when the context cache was converted to use Linux lists.
