[PATCH] freezer: cleanup printk call sequences

[PATCH] freezer: cleanup printk call sequences

[Michael Roth]

Correct and ease printk() interaction among freeze_processes()
and try_to_freeze_tasks().

Move printk("done") in thaw_processes() before schedule() to
prevent implicit interferences from it.
