Fix a side effect of adding xcbc support, when the next_buffer is not
copied.
The issue occurs, when there is stored from previous state a blocksize
buffer and received, a less than blocksize, from user. In this case, the
nents for req->src is 0, and the next_buffer is not copied.
An example is:
{
.tap = { 17, 15, 8 },
.psize = 40,
.np = 3,
.ksize = 16,
}
