Multipath ignores map in use when flushing

[Gorka Eguileor]

When flushing a multipath we are ignoring map in use transient error, so we log a warning that the flush has not been successful and that we have received an exit code 1 and we continue to remove the individual paths.

This error is usually transient and a simple retry will succeed in flushing the multipath.

Failure to retry will leave an empty multipath in our system.
