    eventdev: fix invalid memory free operation

    Fixe the invalid memory free operation caused by extending
    xstats ID width from 32 to 64 bits.

    Telemetry application crashed when freeing memory,
    hence, the telemetry app could not display xstats.

    Fixes: 1bdfe4d76e98 ("eventdev: increase xstats ID width to 64 bits")
