Segfault when using doveadm batch -A : kick
Hi,
Apparently the "kick" doveadm_cmd_ver2 struct lacks a .mail_cmd member
pointing to an appropriate allocation function, causing a NULL pointer
dereference when used via `doveadm batch`.
(gdb) bt
#0 0x in ?? ()
#1 0x55585882 in doveadm_mail_cmd_init (cmd=cmd@entry=0x7fffe680,
set=0x555f2440) at doveadm-mail.c:596
#2 0x55586f68 in cmd_batch_add (argv=, argc=, batchctx=0x55606538) at doveadm-mail-batch.c:78

(gdb) p *cmd
$5 = {alloc = 0x0, name = 0x555bdd0c "kick", usage_args = 0x555be738
"[-a ] [|]"}
