[Dovecot] doveadm stats top exit with error

Hello,

looks like a cosmetical problem but I like to mention it though:

doveadm stats top is interactive. To exit I press as usual CTRL+C and get ^Cdoveadm(root): Error: close(-1[doveadm-stats.c:496]) failed: Interrupted system call

It's dovecot-2.2.10.
