Fix uninitialized value in QEMU monitor FD sending code

The 'char control[CMSG_SPACE(sizeof(int))];' was not being
wiped, so could potentially contain uninitialized bytes.
While this was harmless in this case, it caused complaints
from valgrind

* src/qemu/qemu_monitor.c: memset 'control' variable
  in qemuMonitorIOWriteWithFD
