iommu: Don't overwrite domain pointer when there is no default_domain
IOMMU drivers that do not support default domains, but make
use of the the group->domain pointer can get that pointer
overwritten with NULL on device add/remove.
Make sure this can't happen by only overwriting the domain
pointer when it is NULL.
