s390x/flic: cache flic in s390_get_flic
s390_get_flic() is called many times to obtain the flic. This wastes a lot of time as it calls object_resolve_path() every time. Let's cache S390FLICState by defining it as static. Signed-off-by: Fei Li <sherrylf@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
