fix: set _drive_id_endpoint before early return in SharePointReader._get_drive_id

When drive_id is provided directly to SharePointReader, _get_drive_id()
returned early without setting _drive_id_endpoint, causing AttributeError
in downstream methods like _get_sharepoint_folder_id, _get_permissions_info,
_list_folder_contents, and _list_drive_contents.

Moved the _drive_id_endpoint assignment before the early return checks so
it is always set regardless of how the drive ID is resolved.

Bump llama-index-readers-microsoft-sharepoint version to 0.8.1.
