ITEM_RANDOM_VALUE token initializes 32 bits mask argument value from
a constant source buffer.
Testpmd initiated the mast value from the 3 bytes buffer -
[0xff, 0xff, 0x00].
When testpmd copied that value to 32 bits mask it accessed a memory
byte outside the source buffer.
The patch fixes the source buffer size.
