r8169: fix ASPM-related problem for chip version 42 and 43

Browse source 
Referenced commit missed that for chip versions 42 and 43 ASPM
remained disabled in the respective rtl_hw_start_...() routines.
This resulted in problems as described in the referenced bug
ticket. Therefore re-instantiate the previous logic.

Fixes: 5fc3f6c90c ("r8169: consolidate disabling ASPM before EPHY access")
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217635
