Subject: [PATCH 04/24] compat_ioctl: block: handle BLKGETZONESZ/BLKGETNRZONES

These were added to blkdev_ioctl() in v4.20 but not blkdev_compat_ioctl,
so add them now.

Cc: <stable@...r.kernel.org> # v4.20+
Fixes: 72cd87576d1d ("block: Introduce BLKGETZONESZ ioctl")
Fixes: 65e4e3eee83d ("block: Introduce BLKGETNRZONES ioctl")
