Olaf Faaland 14c240cede Detect long config lock acquisition in mmp ...

If something holds the config lock as a writer for too long, MMP will
fail to issue MMP writes in a timely manner.  This will result either in
the pool being suspended, or in an extreme case, in the pool not being
protected.

If the time to acquire the config lock exceeds 1/10 of the minimum
zfs_multihost_interval, report it in the zfs debug log.
