Subject: Fix uninitialized read in doveadm-oldstats
The third argument to doveadm_cmd_param_bool() is only set on a return
value of TRUE.
Since disk_input_field and disk_output_field should be set if the value
of show-disk-io is specified and specified to true, fix the condition.
doveadm-oldstats.c: In function 'cmd_stats_top':
doveadm-oldstats.c:551:63: warning: 'b' may be used uninitialized [-Wmaybe-uninitialized]
551 | if (!doveadm_cmd_param_bool(cctx, "show-disk-io", &b) && b) {
| ^
doveadm-oldstats.c:545:14: note: 'b' was declared here
545 | bool b;
| ^
