The check condition (csum_result == 0) does not make sense anymore as
it's not the buffer and not the crc32c result as it used to be. The
message does not bring any value and looks like it's some debugging aid
from the old times (added in 2008 as bb7055ec21 ("Add some extra
debugging around file data checksum failures")).

For passing authentication keys to the checksumming functions we need a
container for the key.
Pass in a btrfs_fs_info to btrfs_csum_data() so we can use the fs_info
as a container for the authentication key.
Note this is not always possible for all callers of btrfs_csum_data() so
we're just passing in NULL for now
Functions calling btrfs_csum_data() with a NULL fs_info argument are
currently not supported in the context of an authenticated file system.
