r8169: reset chip synchronously in __rtl8169_resume
Triggering an asynchronous reset is problematic for the following
reasons, therefore reset the chip synchronously.
- The reset routine resets registers and parameters behind our back
what may collide with code executed after triggering the reset.
- __rtl8169_resume() is called as part of pm_runtime_get_sync() and
callers expect that the chip is fully resumed afterwards.
In context of this driver triggering an asynchonous reset should be
considered an emergency procedure.
