HV:change the return type of sbuf_get and sbuf_put

Browse Source 
Because of the return type inconsistent,change the
sbuf return type to uint32_t to fix it,and make the
pre-condition to check the parameter whether is NULL.

V1->V2:
  1.add () to bool expression
  2.add pre-assumption to sbuf_get and sbuf_put
