[GIT PULL] Btrfs updates for 4.17, part 2

[David Sterba]

Hi,

we have queued a few more fixes (error handling, log replay, softlockup)
and the rest is SPDX update that touches almost all files so the
diffstat is long. The top patch is a fixup for excessive warning and
was not in linux-next but I've tested it locally.

Please pull, thanks.
