Allocate a descriptor for each period of a cyclic transfer, not just the first.
Also since the callback needs to be called for each finished period make sure to
initialize the callback and callback_param fields of each descriptor in a cyclic
transfer.

Applied thanks
Thanks.
Btw the switch moved should have return error for default case when direction is
not slave, but thats not in context of this as you moved that code
Checking inside the loop makes the error handling more complicated since at
that point the descriptor is already allocated and needs to be freed again. So
we check this right at the beginning (Using is_slave_direction), so we'll never
get to the loop if the direction is not OK. The default statement is mainly
there to keep the compiler happy.
