similar to: [PATCH v2 12/18] drm/qxl: track primary bo

Track which bo is used as primary surface. With that in place we don't need the primary_created flag any more, we can just check the primary bo pointer instead. Also verify we don't already have a primary surface in qxl_io_create_primary().

Pass the shadow bo to qxl_io_create_primary() instead of expecting qxl_io_create_primary to check bo->shadow. Set is_primary flag on the shadow bo. Move the is_primary tracking into qxl_io_create_primary() and qxl_io_destroy_primary() functions. That simplifies primary surface tracking and the workflow in qxl_primary_atomic_update().

Drop pointless indirection, remove the mem_slots array and index variables, drop dynamic allocation. Store memslots in qxl_device instead.

The encoder callbacks are only called in case the video mode changes. So any layout changes without mode changes will go unnoticed. Add qxl_crtc_update_monitors_config(), based on the old qxl_write_monitors_config_for_encoder() function. Hook it into the enable, disable and flush atomic crtc callbacks. Remove monitors_config updates from all other places. Fixes:

The qxl device supports only a single active framebuffer ("primary surface" in spice terminology). In multihead configurations are handled by defining rectangles within the primary surface for each head/crtc. Userspace which uses the qxl ioctl interface (xorg qxl driver) is aware of this limitation and will setup framebuffers and crtcs accordingly. Userspace which uses dumb

qxl_io_log() sends messages over to the host (qemu) for logging. Remove the function and all callers, we can just use standard DRM_DEBUG calls (and if needed a serial console).

If qxl_device_init fails on creating resources and does not report it, then qxl module will catch null pointer exception on remove, or on probe's error path. The patch adds error path with resources release into qxl_device_init. Found by Linux Driver Verification project (linuxtesting.org).
