spi: Fixes for v4.4

There's one fix for the core here, we weren't reinitialising the actual transferred length in messages when they get reused which meant that we'd just keep adding to the length if a message is reused. This has limited impact since it's only used in error handling cases but will really mess anything that tries to use it up when it triggers.

As ever there's a small collection of driver specific fixes too.
