kasan: disable LOCKDEP when printing reports

If LOCKDEP detects a bug while KASAN is printing a report and if
panic_on_warn is set, KASAN will not be able to finish.  Disable LOCKDEP
while KASAN is printing a report.

See https://bugzilla.kernel.org/show_bug.cgi?id=202115 for an example
of the issue.
