    mbuf: fix packet data read
    
    The sum of offset + length, both 32 bit unsigned integers, could wrap
    around, causing comparisons to give the wrong result.
    This was fixed by using 64 bit instead of 32 bit for calculating the sum.
    
    Note:
    When the branch is not taken for the initial "if ((uint64_t)off + len >
    rte_pktmbuf_pkt_len(m))" comparison, the sum is known to not exceed the
    maximum possible value of rte_pktmbuf_pkt_len(m), UINT32_MAX, and
    following sum calculations can proceed using 32 bit.
    
    Also, fixed a related bug in an mbuf test case:
    It expected reading a length of UINT_MAX from a non-zero offset to not
    fail.
    And due to the offset+length wraparound bug, the read operation did not
    fail.
    This test case was updated to expect the read operation to fail.

    Fixes: 7b295dceea07 ("test/mbuf: add unit test cases")
