stm32/dma: eagerly start transfers when calling the functions.
...
`async fn`s do nothing until polled, but we want the DMA transfer to
immediately start in this case. Drivers rely on it. Some require special
orders, such as "start DMA, start SPI, then wait for DMA" which is awkward
to do without eager start.
Also use a manually-impl'd future, this allows getting rid of the "double"
Unborrow channel clone.

stm32/dma: rename is_stopped to is_running.

Note that this does NOT invert the result of `en()` because it was
wrong before.
