freezer: move frozen_process() to kernel/power/process.c

Browse source 
Other than refrigerator, no one else calls frozen_process().  So move it from
include/linux/freezer.h to kernel/power/process.c.

Also, since a task can be marked as frozen by itself, we don't need to pass
the (struct task_struct *p) parameter to frozen_process().
