[PATCH 1/1] fs: btrfs: avoid superfluous messages

[Heinrich Schuchardt <heinrich.schuchardt@canonical.com>]

Output like the following is quite irritating:

    => bootefi hello
    Scanning disk mmc2.blk...
    No valid Btrfs found
    Bad magic number for SquashFS image.
    ** Unrecognized filesystem type **
    Scanning disk mmc1.blk...
    No valid Btrfs found
    Bad magic number for SquashFS image.
    ** Unrecognized filesystem type **
    Scanning disk mmc0.blk...
    No valid Btrfs found
    Bad magic number for SquashFS image.
    ** Unrecognized filesystem type **

It is expected that most partitions don't contain a Btrfs. This is only
worth a debug message.
