BSON C-Extension: Remove dereference before null check

      Here we're allocating memory for a new buffer, then attempting to call bson_buffer_set_max_size before performing a null check. At this point in this code path, the null check isn't necessary and should be done before we try to set the buffer's max_size.

      bson_buffer_t buffer = bson_buffer_new();
      bson_buffer_set_max_size(buffer, FIX2INT(max_size));
      if (buffer == NULL) {
          rb_raise(rb_eNoMemError, "failed to allocate memory in buffer.c");
      }
