xilinx_axidma: Do not set DMA .notify to NULL after notify
If a stream notify function is not ready, it may re-populate the notify call- back to indicate it should be re-polled later. This break in this usage, as immediately following the notify() call, .notify is set to NULL. reverse the ordering of the notify call and NULL assignment accordingly.
