Arne Welzel 1b3e8a611e ftp/main: Skip get_pending_command() for intermediate reply lines
Intermediate lines of multiline replies usually do not contain valid status
codes (even if servers may opt to include them). Their content may be anything
and likely unrelated to the original command. There's little reason for us
trying to match them with a corresponding command.

OSS-Fuzz generated a large command reply with very many intermediate lines
which caused long processing times due to matching every line with all
currently pending commands.
This is a DoS vector against Zeek. The new ipv6-multiline-reply.trace and
ipv6-retr-samba.trace files have been extracted from the external ipv6.trace.
