Do not fail fetches on unknown attributes

[simo5]

Description

Just ignore the attributes we do not know anythign about.

This is causing a CKR_DEVICE_ERROR on unknown attributes (like CKA_PAREMETER_SET) instead of just returning they are unknown.

code looks good .
For RPM build, we need to bump the toml version. Either bump to 0.9 or just relax the requirements to work with >0.8, <0.10 (preferred).,

Can't support both 0.8 and 0.9, as 0.9 breaks API, so I need to fix more things now ...

then in can be done in separate PR. This is good to go.

it was just a matter of explicitly adding a new feature in Cargo.toml not a real API breakage, so I added it to this PR.

I think it needs to come also here:

The other test looks like the flaky one

[simo5]

@Jakuje Sounds like just upgrading toml does not resolve the RPM issue, so I will drop the commit and leave it to you to investigate

[simo5]

Ah I saw the comment about the workfloow just now, lemme see if that fixes it

[Jakuje]

And it does. Merging. Thanks!
