[PATCH] btrfs-progs: Fix printf format casting errors

[Luca Bruno <lucab@debian.org>]

There are still some warnings of the form:

format '%llu' expects type 'long long unsigned int' but argument has type 'u64'

In conjunction with -Werror, this is causing some build failures.
Now they're properly casted, avoiding compiler warnings.
