vkd3d-shader/sm4: Set "dst_count" to 0 when we clear "dst" in shader_sm4_read_instruction().

VKD3D_SM4_OP_DCL_RESOURCE currently has 1 for "dst_count", but NULL for
"dst". This is largely harmless because we never attempt to access the
destination register of VKD3DSIH_DCL instructions, but nevertheless not
quite proper.
