uapi: linux/blkzoned.h: fix BLKGETZONESZ and BLKGETNRZONES definitions
According to the documentation in include/uapi/asm-generic/ioctl.h,
_IOW means userspace is writing and kernel is reading, and
_IOR means userspace is reading and kernel is writing.
In case of these two ioctls, kernel is writing and userspace is reading,
so they have to be _IOR instead of _IOW.

Fixes: 65e4e3eee83d7 ("block: Introduce BLKGETNRZONES ioctl")
