tdf#106541 doc import: always register listLevel

LFO and listLevel are NOT a required pair.

The path on the Paragraph side is safe to re-enter.
This patch makes the style side safe to re-run
with partial information.

If we don't register immediately, then a non-existant LFO
means that we totally lose the provided listLevel.
So just RegisterNumFormat even though it
likely will be run again by Read_LFOPosition.
