Boris Brezillon a5dfbb2721 drm/panfrost: Don't try to map pages that are already mapped 
commit f45da8204ff1707c529a8769f5467ff16f504b26 upstream.

We allocate 2MB chunks at a time, so it might appear that a page fault
has already been handled by a previous page fault when we reach
panfrost_mmu_map_fault_addr(). Bail out in that case to avoid mapping the
same area twice.
