Marco Widmer 32b4388ba8 drivers: dma: stm32: do not clear busy flag in cyclic mode 
The STM32 DMA driver supports cyclic mode by setting source_reload_en
and dest_reload_en. This causes the dma_callback to be called twice per
buffer run-through, at half-time and when wrapping back to the start of
the buffer.

However, the current implementation only calls dma_callback twice. When
wrapping the first time, it sets stream->busy to false and ignores
subsequent interrupts.

With this change, the busy flag is only cleared in non-cyclic mode.
