tap: do not use strlen on vector
sanitizer complains about strlen on hi->name in tap_dump_ifs. hi->name is a vector which is not null-terminated, so use vec_len. Type: fix Signed-off-by: Vladimir Isaev <visaev@netgate.com> Change-Id: Icdd5f65369bb51b0c4a9cd86c24899e6febd837c (cherry picked from commit 84f3d9fba4e1715237a41f0978430193363187c7)
