ODL connection is closed after disableMultipath()

[xiaofeng6WIND]

This patch fixes the commit 46d1183a0c37("zrpcd: two fixes on enableMultipath/disableMultipath handler").

For enableMultipath/disableMultipath handler, True will be returned with an assigned error in two cases:

• when multipath is already disabled, disableMultipath() is called
• when multipath is already enabled, enableMltipath() is called

In both cases, zrpcd will disconnect peer ODL.
