Allows mmap on dmabuf fd with MAP_SHARED and PROT_WRITE.

This fixes boot failures caused due to mmap() returning error

Commit message is quite meh - xf86-video-omap does not use the API, so
things should work (tm) ;-)
Joking aside - Android and closed source user-space drivers are used,
so please mention that.

Although I'd stick with Rob's input - he is the principal author of this code.

IIRC we had the same problem in amdgpu some time ago, so in general the patch looks correct to me.

Christian.
