[GIT PULL] Block followup fixes for 4.4-rc3

[Jens Axboe <axboe@fb.com>]

Hi Linus,

Wasn't going to send off a new pull before next week, but the blk flush
fix from Jan from the other day introduced a regression. It's rare
enough not to have hit during testing, since it requires both a device
that rejects the first flush, and bad timing while it does that. But
since someone did hit it, let's get the revert into 4.4-rc3 so we don't
have a released rc with that known issue.

Apart from that revert, three other fixes:

- From Christoph, a fix for a missing unmap in NVMe request preparation.

- An NVMe fix from Nishanth that fixes data corruption on powerpc.

- Also from Christoph, fix a list_del() attempt on blk-mq that didn't
  have a matching list_add() at timer start.

Please pull!
