Port the following commit from OpenZFS
7125a109dcc Fix zpool history unbounded memory usage
From that description
In original implementation, zpool history will read the whole history
before printing anything, causing memory usage goes unbounded. We fix
this by breaking it into read-print iterations.
To test this, I did a zfs test run. I also manually verified 'zpool history' is working as expected.
