l2: handle complete clone fail in l2_flood
vlib_buffer_clone(...) may not manage to produce any buffer clones at all. vlib_buffer_clone_256 should not smash the original buffer reference count if no clones are produced. Type: fix Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I14d9d53637a220485c7a0036cfc75a4149b264ea
