drm/udl: use drm_gem_object_put_unlocked. 

When Daniel removed struct_mutex he didn't fix this call to the unlocked
variant which is required since we no longer use struct mutex.

This fixes a bunch of:
WARNING: CPU: 4 PID: 1370 at drivers/gpu/drm/drm_gem.c:931 drm_gem_object_put+0x2b/0x30 [drm]

CPU: 4 PID: 1370 Comm: Xorg Not tainted 5.0.0+ #2

backtraces when you plug in a udl device.
