hw/char: riscv_htif: Use blocking qemu_chr_fe_write_all

The current approach of using qemu_chr_fe_write() and ignoring the
return values results in dropped characters [1]. Ideally we want to
report FIFO status to the guest, but the HTIF isn't a real UART, so we
don't really have a way to do that.

Instead let's just use qemu_chr_fe_write_all() so at least we don't drop
characters.
