shared/ask-password-api: backspace all chars at once

We'd call loop_write() separately for each char. Let's be nice to
serial console users, and write the full string in one go.

Coverity was complaining that we're not checking the return value
from loop_write(). Rework the code a bit and add voidify.
CID#1402323.
