patch2_4: enable poll from hpd_work to avoid races (4.10-rc5)

Gleb,

thanks for testing the patches.
Can you do another two runs on top of 4.10-rc5:
patch2_1 + "nouveau.runpm=0"
and
patch2_1 + patch2_4 (which I'm attaching)

Based on the logs I still think the main issue is the hpd_work and the
poll_work execution ordering, but there might be also locking issues to prevent
races.

Thank you for your time,
Péter
