Fix the benchmark for disable_lp

[open-junius]

Description

The main purpose of the PR is to get the weigth for dissolve_all_liquidity_providers function,
which is called in dissolve_network. I'd like to update it before continue with my dissolve network PR.
The disable_lp also call it, just use the computed weight to set weight of disable_lp extrinsic.
I didn't update the benchmark because later, disable_lp will be removed after balancer implementation https://github.com/opentensor/subtensor/pull/2505/changes#diff-59099c09418a27c73c83511de538c50ab52c17424cfb89582e241c95f0ec9c06.

We should ignore the weight but still propagate the error, I guess?

Add the error handler here.

I get the impression it got modified at the wrong place? I see a propagation at the bottom in the disable_lp but this one is used in a lot of different places. Any reason why we don't want to propagate the error as it was before?

[open-junius]

Yes. I just modified the place after search in the code. I was think the whole dissolve_network will be updated so didn't realize it need change. just fix it.
