page_pool: store detach_time as ktime_t to avoid false-negatives
While testing other changes in vng I noticed that
nl_netdev.page_pool_check flakes. This never happens in real CI.
Turns out vng may boot and get to that test in less than a second.
page_pool_detached() records the detach time in seconds, so if
vng is fast enough detach time is set to 0. Other code treats
0 as "not detached". detach_time is only used to report the state
to the user, so it's not a huge deal in practice but let's fix it.
Store the raw ktime_t (nanoseconds) instead. A nanosecond value
of 0 is practically impossible.
