virtgpu: remove redundant task_comm copying
Remove redundant task name copying because: 1. task->comm is already NUL-terminated 2. virtio_gpu_context_create() trims passed dbgname anyway Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Link: http://patchwork.freedesktop.org/patch/msgid/588612bbc672e8b598e10f79fcbc041122e844ba.1504202471.git.mirq-linux@rere.qmqm.pl Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
