dlm for 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.
dlm: fix invalid cluster name warning

The warning added in commit 3b0e761ba83
  "dlm: print log message when cluster name is not set"

did not account for the fact that lockspaces created
from userland do not supply a cluster name, so bogus
warnings are printed every time a userland lockspace
is created.
