Pass SharedBuffer by reference to DeferredImageDecoder::setData()

Pass SharedBuffer by reference to DeferredImageDecoder::setData()

Pass SharedBuffer by reference to DeferredImageDecoder::setData() as it can
never be null. This gets rid of a few unnecessary null checks. The existing
code would have crashed anyway if the pointer were null as 1 null check was
missing.
