ofproto-dpif: Discard any flow_miss_batches before destroy a ofproto
		
Commit dd2e44f835fac8 fixed a similar race conditions w.r.t.
removal of 'ofproto', but reintroduced this bug. While 'ofproto'
is being removed, the existing flow_miss_batches may still contain
references to the to be removed 'ofproto', causing access to freed
memory.

Bug #1202234
