Description of problem:

When bridge interface is being created, the process makes entry in
::/proc/self/mounts::

###########
## Entry ##
###########
proc net:[4026532264] proc rw,nosuid,nodev,noexec,relatime 0 0
proc net:[4026532264] proc rw,nosuid,nodev,noexec,relatime 0 0


To be more clear, when undercloud deployment is in progress, bridge
interface(br-ctlplane) is created.

Deployment begin with ::openstack undercloud install:: as usual.
The following is log during this creation process.

Just after showing this log, above ::Entry:: appear to me.

Same ::Entry:: is created when using ::packstack::
This ::Entry:: has ::SNMPd:: log the following message 
periodically in ::syslog:: except OSP6.

It's because SNMPd is not active in OSP6.

This message never stops because there is ::Entry:: always
but ::statfs:: can not find any mount point which suggested by 
::Entry::

If the ::Entry:: is not necessary, it's better to get rid of it, 
or log message more appropriately.

If I've been missing anything, please point it out to me.
