Martine Lenders 57d3c4698c gcoap: don't drop observer on re-register
With #9209 gCoAP got the ability to re-register and OBSERVE with a new
token, sadly the `observer` variable wasn't set in that fix, so a
re-registration actually led to the deletion of the observer (because it
is still `NULL` when the old registration is overwritten in l. 317)
