iris: don't bump the seqno for the workaround_bo

Browse Source 
The last_seqnos list is used by iris_emit_buffer_barrier_for() and as
far as I can understand we don't emit barriers for the workaround bo,
so don't even bother doing the atomic operations required to bump the
workaround_bo seqno list.
