Johan Hovold 8e47f51af8 drm/msm: fix memleak on release ...

commit a64fc11b9a upstream.

If a process is interrupted while accessing the "gpu" debugfs file and
the drm device struct_mutex is contended, release() could return early
and fail to free related resources.

Note that the return value from release() is ignored.
