Dan Carpenter e46ad8b298 drm/msm: uninitialized variable in msm_gem_import() ...

[ Upstream commit 2203bd0e5c ]

The msm_gem_new_impl() function cleans up after itself so there is no
need to call drm_gem_object_put().  Conceptually, it does not make sense
to call a kref_put() function until after the reference counting has
been initialized which happens immediately after this call in the
drm_gem_(private_)object_init() functions.

In the msm_gem_import() function the "obj" pointer is uninitialized, so
it will lead to a crash.
