Revert of Enable dark_resume_always workaround if the wake-on-packets flag is set (patchset #4 id:60001 of https://codereview.chromium.org/589723003/)
Revert of Enable dark_resume_always workaround if the wake-on-packets flag is set (patchset #4 id:60001 of https://codereview.chromium.org/589723003/)

Reason for revert:
Kernel changes have landed.  This workaround is no longer needed.

Original issue's description:
> Enable dark_resume_always workaround if the wake-on-packets flag is set
>
> The dark_resume_always workaround is necessary for testing
> wake-on-packets functionality because the mechanism to actually query
> the wakeup source is not ready yet.  This workaround tells the kernel to
> always enter dark resume and rely on chrome and powerd to detect user
> activity and transition into fully resumed.
