netfilter: xt_u32: validate user space input
The xt_u32 module doesn't validate the fields in the xt_u32 structure.
An attacker may take advantage of this to trigger an OOB read by setting
the size fields with a value beyond the arrays boundaries.
Add a checkentry function to validate the structure.
This was originally reported by the ZDI project (ZDI-CAN-18408).
