[PATCH] hw/block/nvme: remove description for zoned.append_size_limit

[PATCH] hw/block/nvme: remove description for zoned.append_size_limit

[Niklas Cassel]

From: Niklas Cassel <niklas.cassel@wdc.com>

The description was originally removed in commit 578d914b263c
("hw/block/nvme: align zoned.zasl with mdts") together with the removal
of the zoned.append_size_limit parameter itself.

However, it was (most likely accidentally), re-added in commit
f7dcd31885cb ("hw/block/nvme: add non-mdts command size limit for verify").

Remove the description again, since the parameter it describes,
zoned.append_size_limit, no longer exists.

I don't see it in nvme-fixes yet.

Did it get stuck in purgatory? ;)


Kind regards,

I could have included it for the PULL from yesterday, but I kinda forgot
and only added the coverity fixes. That's pulled now, so I've queued it
up for the next round of fixes now! :)

Thanks for following up on it!
