When saving a new or existing Disk IO discovery rule, if the Create a separate check for each physical disk value was not enabled then all of the other values (summary, LVM, etc) would be set to enabled after saving.

This fix restores the correct behavior no matter whether Create a separate check for each physical disk is enabled or not.

If no Disk IO discovery rule was added to your site or if you enabled the Create a separate check for each physical disk flag on each rule, then this fix won't affect you.

Otherwise, you will have to edit your rule(s) again to fix the incorrectly saved values from before the update.
