The problem has been introduced by:

    radv: do not use the availability bit for timestamp queries

    It's unnecessary because we can just check if the timestamp
    is to different to the default value when a pool is created
    or resetted. Instead of waiting for the availability bit to
    be 1, we have to emit a not equal WAIT_REG_MEM for checking
    if the timestamp is ready.
