Silvio Cesare b7261fc5f5 UBIFS: Fix potential integer overflow in allocation 
commit 353748a359f1821ee934afc579cf04572406b420 upstream.

There is potential for the size and len fields in ubifs_data_node to be
too large causing either a negative value for the length fields or an
integer overflow leading to an incorrect memory allocation. Likewise,
when the len field is small, an integer underflow may occur.
