Dominik Röttsches a5f6f869e8 Drop layout table if layout lookup accelerator allocation failed 
If the table is kept, when the table is present but only the accelerator
allocation failed, then we run into nullptr dereferences downstream in
hb_ot_map_t::apply when trying to access proxy.accels[i].

To fix this, instead of only setting lookup_count of accelerator_t
itself, drop the whole table to avoid hb-ot-map construction assuming
that the lookups will work correctly despite accelerator allocation
having failed.
