Subject: [PATCH 2/2] arping: Fix unsolicited ARP regressions on -c > 1

4db1de6 tried to fix a regression 1 sec delay due poll() for unsolicited
ARP, .i.e. -A and -U (introduced in 67e070d, reported as issue #536).
But skipping the while loop entirely introduced another regression for
-A and -U, which behave like -c1 (sending *always* only a single packet).

Fixing it by checking in while loop and comparing also count (as it was
done in 67e070d before the rewrite).

NOTE: use exit_loop with continue instead of simple break to keep things
consistent.

Fixes: 4db1de6 ("arping: Fix 1s delay on exit for unsolicited arpings")
Fixes: 67e070d ("arping: use signalfd() and timerfd() rather than signals")
Fixes: https://github.com/iputils/iputils/issues/536
Closes: https://github.com/iputils/iputils/pull/543
Fixes: bsc#1224877
