net: page_pool: report when page pool was destroyed
Report when page pool was destroyed. Together with the inflight
/ memory use reporting this can serve as a replacement for the
warning about leaked page pools we currently print to dmesg.
Example output for a fake leaked page pool using some hacks
in netdevsim (one "live" pool, and one "leaked" on the same dev):
$ ./cli.py --no-schema --spec netlink/specs/netdev.yaml \
--dump page-pool-get
[{'id': 2, 'ifindex': 3},
{'id': 1, 'ifindex': 3, 'destroyed': 133, 'inflight': 1}]
