drm/qxl: Remove empty qxl_gem_prime_mmap()

Browse Source 
The function qxl_gem_prime_mmap() returns an error. The two callers
of gem_prime_mmap are drm_fbdev_fb_mmap() and drm_gem_dmabuf_mmap(),
which both already handle NULL-callbacks with an error code. So clear
gem_prime_mmap in qxl and remove qxl_gem_prime_mmap().
