MAINT: Don't make inapplicable conditions block oneDAL usage in LogisticRegression

[david-cortes-intel]

Description

This PR modifies the checks for whether oneDAL will be supported for logistic regression so as not to block its usage in the following scenarios:

• Passing multi_class strategy argument when the data is binary (argument is ignored).
• Passing an l1 ratio of zero instead of not changing it from the default (it means 'don't apply L1 regularization').

---

PR should start as a draft, then move to ready for review state after CI is passed and all applicable checkboxes are closed.
This approach ensures that reviewers don't spend extra time asking for regular requirements.

You can remove a checkbox as not applicable only if it doesn't relate to this PR in any way.
For example, PR with docs update doesn't require checkboxes for performance while PR with any change in actual code should have checkboxes and justify how this code change is expected to affect performance (or justification should be self-evident).

Should be a quick PR to approve, should wait until private CI is back. Could you add info in the description about the change in warm_start too?

Edit: wrong about warm start, please disregard
