[PATCH] fs: jffs2: fix error value sign

[Vasiliy Kulikov]

do_verify_xattr_datum(), do_load_xattr_datum(), load_xattr_datum()
and verify_xattr_ref() should return negative value on error.
Sometimes they return EIO that is positive.  Change this to -EIO.

 This driver is not compilable, so the patch is not tested.
