r8169: prepare rtl_hw_aspm_clkreq_enable for usage in atomic context
[ Upstream commit 49ef7d846d4bd77b0b9f1f801fc765b004690a07 ]
Bail out if the function is used with chip versions that don't support
ASPM configuration. In addition remove the delay, it tuned out that
it's not needed, also vendor driver r8125 doesn't have it.
