Florian Weimer f5c65fa920 libio: Update number of written bytes in dprintf implementation ...

The __printf_buffer_flush_dprintf function needs to record that
the buffer has been written before reusing it.  Without this
accounting, dprintf always returns zero.

Fixes commit 8ece45e4f5
("libio: Convert __vdprintf_internal to buffers").
