[PATCH v3 4/6] xl: Return an error on failed cd-insert

[George Dunlap <george.dunlap@eu.citrix.com>]

This makes xl more useful in scripts.

The strange thing about this is that the internal cd_insert function
*already* returned something appropriate, and cd-eject was using it,
but cd-insert wasnt.
