[GIT PULL] Btrfs fixes for 4.10

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

Hi Chris,

Here follows a small list of fixes a couple cleanups for the 4.10 merge
window. It contains all the patches from the previous pull request (which
got unanswered nor were the changes pulled yet apparently). The most important
change is still the fix for the extent tree corruption that happens due to
balance when qgroups are enabled (a regression introduced in 4.7 by a fix for
a regression from the last qgroups rework). This has been hitting SLE and
openSUSE users and QA very badly, where transactions keep getting aborted when
running delayed references leaving the root filesystem in RO mode and nearly
unusable.
There are fixes here that allow us to run xfstests again with the integrity
checker enabled, which has been impossible since 4.8 (apparently I'm the
only one running xfstests with the integrity checker enabled, which is useful
to validate dirtied leafs, like checking if there are keys out of order, etc).
The rest are just some trivial fixes, most of them tagged for stable, and two
cleanups.

Thanks.
