Unfortunately, https://github.com/open-mpi/ompi/pull/6797 was merged
before all feedback was received (39b799d936). This PR is a minor
addendum to that commit.
This PR simply removes a meaningless `= {0}` operation.
The use of gethostname() here -- and many other places in the code
base -- is technically unsafe. See
https://github.com/open-mpi/ompi/issues/6801 for a further description
of the issue and a suggested fix. But the risk is quite low;
real-world hostnames are usually much shorter than
OPAL_MAXHOSTNAMELEN. Hence, this PR just removes the meaningless
operation and leaves a real fix for gethostname() usage to a potential
future PR.
