btrfs: Suppress the message about missing filesystem

Browse Source 
This message comes up a lot when scanning filesystems. It suggests to the
user that there is some sort of error, but in fact there is no reason to
expect that a particular partition has a btrfs filesystem. Other
filesystems don't print this error.

Turn it into a debug message.
