The problem is that we are not doing this at the moment,
spice_set_session_option() will set v->verifyop to
SPICE_SSL_VERIFY_OP_HOSTNAME | SPICE_SSL_VERIFY_OP_SUBJECT if a
host subject was specified. VirtViewerSessionSpice::fill_session()
will do the same, and I suspect it's the same for the controller code.
The only reason to specify a host subject is when we know the hostname will
not be correct to verify the host TLS certificate.

If we want to use your patch, we need to change v->verifyop prior to the SSL
verification to remove SPICE_SSL_VERIFY_HOSTNAME when both
SPICE_SSL_VERIFY_OP_HOSTNAME and SPICE_SSL_VERIFY_OP_SUBJECT are set.
