The following fixes compilation of mn10300 which broke when the
interface to flow_loops_find changed (as reported in a comment
in PR56294).  I took the liberty to use the proper interface
for initializing the loop tree.

Built a mn10300 cc1, committed as obvious.

Richard.

	Fix loop discovery code.
