vlib: fix vlib_buffer_free_inline() AVX-512 overflow
'queue' is declared on the stack and must be big enough to handle queue_size + max processed elements per loops. When AVX-512 was added, this additional max was not increased from 4 to 8 accordingly. Type: fix Fixes: 767a9ab4b1 Change-Id: I15f2f930fc316f92da2e4642f41852d856c06a48 Signed-off-by: Benoît Ganne <bganne@cisco.com>
