Chris Metcalf b4287df829 drivers/tty/hvc/hvc_tile.c: properly return -EAGAIN ...

We were returning zero if no bytes could be written to the Tilera
hypervisor console device, but this causes the output to be truncated.
By returning -EAGAIN the tty hvc driver will come back and try again,
which gives the semantics we want, and avoids dropping console output.
