Change locking policy of mmap() callback, making exporters responsible

that dma-buf is locked for both importers and exporters by the dma-buf

self-imported dma-bufs which required to take the lock from the DRM
exporter side.

Christian, you acked the drm patch of this series sometime ago, perhaps
it also implies implicit ack to this patch, but I'd prefer to have the
explicit ack. I'll apply this series to drm-misc later this week if
you'll approve this dma-buf change. Thanks in advance!
I'll merge the patches tomorrow. If there are any additional comments,
then please don't hesitate to post them.
Sorry for not responding earlier, I have been moving both my office as
well as my household and still catching up.
I don't have time for an in-deep review, but my ack stands for the whole
series.
Regards,
Christian.
