[PATCH -mm 3/3] Freezer: Remove redundant check in try_to_freeze_tasks

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@xxxxxxx>

We don't need to check if todo is positive before calling time_after() in
try_to_freeze_tasks(), because if todo is zero at this point, the loop will
be broken anyway due to the while () condition being false.
