[PATCH] opensm/osm_qos_parser_y.y: fix endless loop

[Sasha Khapyorsky <sashak-smomgflXvOZWk0Htik3J/w@public.gmane.org>]

Fix endless loop introduced by signed --> unsigned conversion (was done
for compilation warning fix). Reimplement __parser_strip_white() in
slightly shorter variant without explicit index.
