Patch ready for merging.

v4:

 - check return code of tsk_fs_attr_walk
 - pass TSK_FS_FILE_WALK_FLAG_NOSPARSE as additional flag to tsk_fs_attr_walk

After discussing with TSK authors the behaviour is clear. [1]

In case of COMPRESSED blocks, the callback will be called for all the attributes
no matter whether they are on disk or not (sparse). In such cases, the block
address will be 0. [2]

So we do not have to enforce the blocks to be RAW as we would be missing
COMPRESSED ones (NTFS only).
