[PATCH 07/16] freezer: don't distinguish nosig tasks on thaw

[Tejun Heo <tj@kernel.org>]

There's no point in thawing nosig tasks before others.  There's no
ordering requirement between the two groups on thaw, which the staged
thawing can't guarantee anyway.  Simplify thaw_processes() by removing
the distinction and collapsing thaw_tasks() into thaw_processes().
This will help further updates to freezer.
