[PATCH] drm/etnaviv: remove BUG_ON in MMU unmap path

[Lucas Stach]

If the MMU map fails caused by an unaligned SG entry, the unmap path
is called to undo all already setup SG mappings. When encountering the
unaligned SG the unmap path hangs the kernel with a BUG(), while the
error is recoverable by just failing the submit that references the
faulty object.
