suspend: fix freeze hangup which caused by insmod [1/1]

PD#TV-10472

Problem:
When system on, enter freeze mode lead to flush deferd probe.
Init.rc also run insmod in parallel, if insmod task
atomic_inc(&probe_count), and this task is freezed,
deadlock happends.

Solution:
Move flush deferd probe action before freeze task

Verify:
X32A0-T972
