[PATCH] drm/amd/display: delete unnecessary check in dcn35_set_long_vblank()

[Dan Carpenter]

"timing" is "&pipe_ctx[i]->stream->timing" where ->timing is not the
first struct member of ->stream.  So it's the address which points into
the middle of a struct.  It can't be NULL so delete the NULL check.
