ipfrag: really prevent allocation on netns exit
[ Upstream commit f6f2a4a2eb92bc73671204198bb2f8ab53ff59fb ]
Setting the low threshold to 0 has no effect on frags allocation,
we need to clear high_thresh instead.
The code was pre-existent to commit 648700f76b03 ("inet: frags:
use rhashtables for reassembly units"), but before the above,
such assignment had a different role: prevent concurrent eviction
from the worker and the netns cleanup helper.
Fixes: 648700f76b03 ("inet: frags: use rhashtables for reassembly units")
