vl: add missing display_remote++ 

We should also consider -display vnc= as setting up a remote display,
and not attempt to add another default one.

The display_remote++ in qemu_setup_display() isn't necessary at this
point, but is there for completeness and further usages of the variable.

Fixes: https://gitlab.com/qemu-project/qemu/-/issues/1988
Fixes: commit 484629fc81 ("vl: simplify display_remote logic ")
