refactor: simplify enabled-state check in validateExAppRequestToNC

[oleksandr-nc]

Drops the if (!$isDav) wrapper around the path-info

The branch was a leftover from the old API-scope system (removed in #373) — there's nothing left for it to gate.

Net: -2 lines, one less branch, single code path for OCS and DAV.
