drm/drm_dp_mst:remove set but not used variable 'origlen'
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/gpu/drm/drm_dp_mst_topology.c:3693:16: warning: variable
‘origlen’ set but not used [-Wunused-but-set-variable]
int replylen, origlen, curreply;
It looks like never use variable origlen after assign value to it.
Fixes: ad7f8a1f9c
