[RFA] Fix a small memory leak in bpstat_stop_status

This is a followup on a thread that I started, archived at:
http://sources.redhat.com/ml/gdb-patches/2002-12/msg00358.html

Basically, I extracted the part that fixed a small memory leak, and
tested it separately, as the other part of the patch is likely to be
superseeded by another patch submitted by Klee Dienes.

        * breakpoint.c (bpstat_stop_status): Fix a small memory leak.

No regressions on x86-linux.

Ok to apply?
