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.
