The problem is that currently we don't have any check on the
configured port range. A port range == -1 triggers the bug, while
other negative values may require a very long time to complete the
following loop.

This commit addresses the issue swapping the two ends on negative
ranges. The check is performed in nf_nat_l4proto_unique_tuple() since
the nft nat loads the port values from nft registers at runtime.

v1 -> v2: use the correct 'Fixes' tag
v2 -> v3: update commit message, drop unneeded READ_ONCE()

Fixes: 5b1158e909 ("[NETFILTER]: Add NAT support for nf_conntrack")
