btrfs: don't print the crc32c implementation at module load time

Btrfs can use various different checksumming algorithms, and prints
the one used for a given file system at mount time.  Don't bother
printing the crc32c implementation at module load time, the information
is available in /sys/fs/btrfs/FSID/checksum.
