skd: Initialize skd_special_context.req.n_sg to one
The debug code in skd_send_special_fitmsg() assumes that req.n_sg represents the number of S/G descriptors. However, skd_construct() initializes that member variable to zero. Set req.n_sg to one such that the debugging code in skd_send_special_fitmsg() works as expected.
