[PATCH] arc: Fix ARI warning for printf(%p)

[Anton Kolesov <Anton.Kolesov@synopsys.com>]

This particular warning is printed only when option -Wari is passed to
contrib/ari/gdb_ari.sh , so it slipped under my radar.

Ok to commit?

Replace printf ("%p") with printf ("%s", host_address_to_string ()). Printing
host address might make sense here because printed pointers can be null and
this would affect how arc_return_value behaves.
