MINOR: buffer: b_set_data() doesn't truncate output data anymore

b_set_data() is used :
  - in proto_http and hlua to trim input data (b_set_data(co_data()))
  - in SPOE to append data to a buffer while building a message

In no case will this truncate a buffer so we can safely remove the
test for len < b->output.
