[GIT PULL] Block fixes for 5.14-final

Hi Linus,

- Revert the mq-deadline priority handling, it's causing serious
  performance regressions. While experimental patches exists to fix this
  up, it's too late to do so now. Revert it and re-do it properly for
  5.15 instead.

- Fix a NULL vs IS_ERR() regression in this release (Dan)

- Fix a mq-deadline accounting regression in this release (Bart)

- Mark cryptoloop as deprecated. It's broken and dm-crypt fully supports
  it, and it's actively intefering with loop. Plan on removal for 5.16.
  (Christoph)
