Alexander Motin 2cb74ed856 Skip VDEV_IO_DONE stage only for ZIO_TYPE_FREE. ... Device removal code uses zio_vdev_child_io() with ZIO_TYPE_NULL parent, that never happened before. It confused FreeBSD-specific TRIM code, which does not use VDEV_IO_DONE for logical ZIO_TYPE_FREE ZIOs. As result of that stage being skipped device removal ZIOs leaked references and memory that supposed to be freed by VDEV_IO_DONE, making it stuck. It is a quick patch rather then a nice fix, but hopefully we'll be able to drop it all together when alternative TRIM implementation finally get landed.
