[Users] vdsm netinfo fails errors with InfiniBand present

[Trey Dockendorf]

Just realized mailing list was not CCed.

https://bugzilla.redhat.com/show_bug.cgi?id=1063433 has been filed
regarding the patch.

I had to apply using 'patch -d /usr/lib64/python2.6/site-packages -p2
< 0001-netinfo.speed-avoid-log-spam.patch', and verified it works.

Will file the IB bug report shortly.
