trivial diff: MR_do_trace_redo_fail bug fix

[Fergus Henderson]

Estimated hours taken: 0.75

runtime/mercury_trace_base.c:
	Fix a bug: it was calling init_label() instead of init_entry()
	for MR_do_trace_redo_fail.  This allowed gcc to optimize
	away that entry point, resulting in link errors for programs
	that used it (i.e. nondet programs compiled with tracing
	enabled).
