block: Reset buffer alignment on detach
BlockDriverState member buffer_alignment is initially 512. The device
model may set them, with bdrv_set_buffer_alignment(). If the device
model gets detached (hot unplug), the device's alignment is left
behind. Only okay because device hot unplug automatically destroys
the BlockDriverState. But that's a questionable feature, best not to
rely on it.
