nouveau: fix missing locking in call to drm_gem_object_unreference drm_gem_object_unreference is called without locking in nouveau_gem.c:nouveau_gem_ioctl_new(). Linux commit bc9025bdc4e2b591734cca17697093845007b63d replaces the call with a call to drm_gem_object_unreference_unlocked() which was introduced in 2.6.34. To avoid having to backport core DRM stuff from 2.6.34, just fix the locking instead.
