char: convert qemu_chr_fe_write to qemu_chr_fe_write_all

The mux chardev was not checking the return value of any
qemu_chr_fe_write() call so would silently loose data
on EAGAIN.

Similarly the qemu_chr_fe_printf method would not check
errors and was not in a position to retry even if it
could check.
