nfp: abm: remember which Qdisc is root
Keep track of which Qdisc is currently root. We need to implement
TC_SETUP_ROOT_QDISC handling, and for completeness also clear the
root Qdisc pointer when it's freed. TC_SETUP_ROOT_QDISC isn't always
sent when device is dismantled.
Remembering the root Qdisc will allow us to build the entire hierarchy
in following patches.
