[PATCH] Fix uninitialized value in QEMU monitor FD sending code

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

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
