netfilter: nf_tables: add reschedule during chain loop detection
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2219421 Upstream Status: all upstream
On debug kernel with large ruleset restore the chainloop detection can take a very long time to complete.
Add a schedule call to avoid softlockup warning.
