  Log Message:
  -----------
  dpif-netlink: Fix multiple-free and fd leak on error path.

This function attempts to open a bunch of new handlers.  If it fails, it
attempts to close all the handlers that have already been opened.
Unfortunately, the loop to close the opened handlers used the wrong array
index: 'i' instead of 'j'.  This fixes the problem.
