[PATCH 9/9] ch_driver: Handle validation failure correctly

[William Douglas <william.douglas@xxxxxxxxx>]

When validation like deviceValidateCallback fails, the vm will not be
set and so the call to virDomainObjListRemove will be passed a NULL
pointer causing a segfault. To prevent this add a check that the vm is
defined before calling out to virDomainObjListRemove.
