[GIT PULL] Fixes for 4.0-rc

[Jens Axboe]

Hi Linus,

A small collection of fixes that has been gathered over the last few
weeks. It contains:

- A one-liner fix for NVMe, fixing a missing list_head init that could
  makes us oops on hitting recovery at load time.

- Two small blk-mq fixes:
        - Fixup a bad goto jump on error handling.
        - Fix for oopsing if running out of reserved tags.

- A memory leak fix for NBD.

- Two small writeback fixes from Tejun, fixing a missing init to
  INITIAL_JIFFIES, and a possible underflow introduced recently.

- A core merge fixup in sg gap detection, where rq->biotail was indexed
  with the count of rq->bio.

Please pull!
