gpt-auto: properly handle case where we can't determine devno of /usr/ fs

get_block_device_harder() returns == 0 if the fs is valid, but it is not
backed by a single devno. (As opposed to returning > 0 if the devno is
valid). Let's catch this case and log a clear message, and don't bother
open the device in that case.

This is mostly cosmetical, as either way, systemd-gpt-auto-generator
doesn't work in scenarios like that.
