jffsX-utils: fix integer overflow in jffs2dump.cHEADmaster
Report of the static analyzer: The value of an arithmetic expression 'datsize + oobsize' is a subject to overflow because its operands are not cast to a larger data type before performing arithmetic. Corrections explained: - Added a check to validate datsize and oobsize to ensure they are non-negative and within a safe range. - Cast datsize and oobsize to long before performing arithmetic to prevent potential integer overflow. This change ensures safe computation of offsets and prevents undefined behavior caused by overflow.
