multiple "xfrd: zone %s written received XFR packet from %s with serial %u to " logged

[ttyS4]

xfrd.c:#L2472 is where this message is logged.

I believe the intention is to log only on the last because of the if statement: zone->latest_xfr->msg_seq_nr == 0 however there is no { and } it is a naked if statement

Probably only a few uses verbosity level 4 like I do so no one noticed.
