Security fix for byte slices

Adding changes to slice only the first 16 bytes of
the mIrk field when serializing. When deserializing
we only get the first 16 bytes when reading, therefore
it is not necessary to serialize the entire array when
writing

Bug: 244569009
Test: Sample Android App mentioned in the bug
