PM: sleep: Avoid using pr_cont() in the tasks freezing code
commit a449dfbfc0894676ad0aa1873383265047529e3a upstream.
Using pr_cont() in the tasks freezing code related to system-wide
suspend and hibernation is problematic, because the continuation
messages printed there are susceptible to interspersing with other
unrelated messages which results in output that is hard to
understand.
Address this issue by modifying try_to_freeze_tasks() to print
messages that don't require continuations and adjusting its
callers accordingly.
