qemu: Refactor qemuDomainGetChardevTLSObjects to converge code

Browse Source 
Create a qemuDomainAddChardevTLSObjects which will encapsulate the
qemuDomainGetChardevTLSObjects and qemuDomainAddTLSObjects so that
the callers don't need to worry about the props.

Move the dev->type and haveTLS checks in to the Add function to avoid
an unnecessary call to qemuDomainAddTLSObjects
