MINOR: stconn: add sc_hastream() and __sc_hastream() helpers

Browse source 
This patch introduces the sc_hastream() and __sc_hastream() inline
helpers to retrieve a haload stream context (struct hastream) from
a stream connector.

These functions allow the stconn layer to safely access haload-specific
stream data when the application type is OBJ_TYPE_HXLOAD.
