hush: fix segfault on syntax error
Hush segfaults if it sees a syntax error while attempting to parse a
command:
$ ./u-boot -c "'"
...
syntax error
Segmentation fault (core dumped)
This is due to a NULL pointer dereference of in_str->p in static_peek().
The problem is that the exit condition for the loop in
parse_stream_outer() checks for rcode not being -1, but rcode is only
ever 0 or 1.
