dmaengine: at_hdmac: Fix descriptor handling when issuing it to hardware
commit ba2423633ba646e1df20e30cb3cf35495c16f173 upstream.
As it was before, the descriptor was issued to the hardware without adding
it to the active (issued) list. This could result in a completion of other
descriptor, or/and in the descriptor never being completed.
Fixes: dc78baa2b90b ("dmaengine: at_hdmac: new driver for the Atmel AHB DMA Controller")
