Since David Herrmann's mmap vma manager rework we don't need to grab dev->struct_mutex any more to prevent races when looking up the mmap offset. Drop it and instead don't forget to use the unref_unlocked variant (since the drm core still cares).

While at it also fix a leak when this ioctl is called on an imported buffer.
