ofproto-dpif-mirror: Fix insane waste of memory and time in checking VLANs.

When a mirror was restricted to particular VLANs, this code was allocating,
copying, and freeing a 512-byte block of memory just to check the value of
a single bit in the block.  This fixes the problem.

Found by inspection.
