[PATCH] fs/squashfs: Set ret to 0 on successful read

[Michael Zimmermann]

It might still be a positive number due to the call to sqfs_disk_read.
This only happens when reading a file from an uncompressed squashfs.

I found this by trying to boot using the extlinux bootmethod, where
positive values are treated as errors.
