[GIT PULL] MD update for 4.13

[Shaohua Li]

Hi,
Please pull MD update for 4.13. This update only includes several bug fixes:

- Neil Brown fixes a deadlock in MD suspend and a potential bug in bio allocation.
- Mikulas Patocka fixes a signal issue
- Guoqing Jiang fixes a typo in FailFast test
- Other trival fixes

Please note, there is a merge conflict with block tree and causes build error,
which could be fixed by this one:

diff --git a/drivers/md/md.c b/drivers/md/md.c
