When bonding module is loaded with primary parameter and one decides to unset
primary slave using sysfs these settings are not preserved during bond device
restart. Primary slave is only unset once and it's not remembered in
bond->params structure.

	I think the patch is fine, although I did prefer the longer
commit message from the initial version (the one that explained how to
reproduce the problem).

Jay,

just to be sure, do you want me to resend this patch again with the
original commit message? It's no problem for me, I just don't want

	Yes.  Detailed commit messages are not spam.
