[Drbd-dev] [PATCH 5/6] crm-fence-peer.sh: Modify empty string assignment statements

[Bart Van Assche]

This patch does not change any functionality but avoids that
shellcheck reports the following warning:

  warning: Remove space after = if trying to assign a value (for empty string, use var='' ... ). [SC1007]
