[PATCH v2] lxc: fix lxcContainerMountAllFS() DEREF_BEFORE_CHECK
vmDef->fss[i]->src->path may be NULL,
so check is needed before passing it to VIR_DEBUG.
Also removed checking vmDef->fss[i]->src for NULL, since it may not be NULL.
Fixes: 57487085dc ("lxc: don't try to reference NULL when mounting
filesystems")
