[libvirt] [PATCH v2/1] qemu: Move TCP and haveTLS checks into qemuDomainDelChardevTLSObjects

[John Ferlan]

Similar to qemuDomainAddChardevTLSObjects let's move the chardev
source must be TCP and it has the @haveTLS flag set checks before
trying to delete the TLS objects.

For the Chr device this represents no change; however, for RNG device
this is an additionaly check that was missed in commit id '68808516'.
Before adding the objects, TCP and haveTLS are checked.

 Thanks for the review... Of course after re-reading my own patch "in
 the morning" I realized I could/should have taken the next step to check
 the chardev source for TCP and haveTLS being set similar to how the Add
 code does things. So that's what this patch does.
