drm/msm: fix memleak on release
commit a64fc11b9a520c55ca34d82e5ca32274f49b6b15 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.
