Returning -1 can cause squashfs v3 detection to make v4 detection fail.

Detect squashfs version <= 3 as squashfs3 and version >= 4 as squashfs.
squashfs kernel module version 4.0 (kernel 2.6.29) is not backward
compatible to open squashfs created with previous versions.
Also fixed version number parsing, see
$ mkdir test
$ mksquashfs test test.sqsh
$ blkid -p test.sqsh
- test.sqsh: VERSION="1024.0" TYPE="squashfs" USAGE="filesystem"
+ test.sqsh: VERSION="4.0" TYPE="squashfs" USAGE="filesystem"

With the previous patch the scanning functions were
modified to return a differentiated return code.
To correctly abort scanning when an I/O error occurs
we need to differentiate between 'error' (= -1) and
'not found' (= 1) in the probe functions.
This patch updates all superblock scanning functions
to the new calling convention.
