Revert "qemu: Use heads parameter for QXL driver"

This reverts commit 7b401c3bdacdf8367a0070e625d73eafb802045d.

Until libvirt is able to differentiate whether heads='1' is just a
leftover from previous libvirt or whether that's added by user on
purpose and also whether the domain was started with the support for
qxl's max_outputs, we cannot incorporate this patch into the tree
due to compatibility reasons.
