multi-process: Initialize variables declared with g_auto*
Quote docs/devel/style.rst (section "Automatic memory deallocation"):
* Variables declared with g_auto* MUST always be initialized,
otherwise the cleanup function will use uninitialized stack memory
Initialize @name properly to get rid of the compilation error (using
gcc-7.3.0 on CentOS):
../hw/remote/proxy.c: In function 'pci_proxy_dev_realize':
/usr/include/glib-2.0/glib/glib-autocleanups.h:28:3: error: 'name' may be used uninitialized in this function [-Werror=maybe-uninitialized]
g_free (*pp);
^~~~~~~~~~~~
../hw/remote/proxy.c:350:30: note: 'name' was declared here
g_autofree char *name;
^~~~
