bonding: fix multiple module load problem

[ Upstream commit 130aa61a77b8518f1ea618e1b7d214d60b405f10 ]

Some users still load bond module multiple times to create bonding
devices.  This accidentally was broken by a later patch about
the time sysfs was fixed.  According to Jay, it was broken
by:
   commit b8a9787eddb0e4665f31dd1d64584732b2b5d051

     bonding: Allow setting max_bonds to zero

Note: sysfs and procfs still produce WARN() messages when this is done
so the sysfs method is the recommended API.
