Alexander Motin 5a3bffab10 ZIO: Optimize zio_flush() ...

- Generalize vdev_nowritecache handling by traversing through the
VDEV tree and skipping children ZIOs where not supported.
 - Remove intermediate zio_null() in case of several VDEV children.
 - Remove children handling from zio_ioctl().  There are no other
use cases for this code beside DKIOCFLUSHWRITECACHED, and would there
be, I doubt they would so straightforward apply to all VDEV children.

Comparing to removed previous optimization this should improve cases
of redundant ZILs/SLOGs.
