[GIT PULL] dlm updates for 4.21

[David Teigland]

Hi Linus,

Please pull dlm updates from tag:

git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-4.21

This set is entirely trivial fixes, mainly around correct cleanup
on error paths and improved error checks.  One patch adds scheduling
in a potentially long recovery loop.

Thanks,
Dave
