xen/scsiback: correct frontend counting

Browse Source 
commit f285aa8db7 upstream.

When adding a new frontend to xen-scsiback don't decrement the number
of active frontends in case of no error. Doing so results in a failure
when trying to remove the xen-pvscsi nexus even if no domain is using
it.
