    system/posix-acl: Unwind with NULL xdata on error

    In posix-acl when there are errors xdata that comes as part of input is
used to
    unwind which can be used as response xdata which may lead to problems as
the
    keys in the input will match with keys in the output but the values the
    response xdata may expect can be completely different.

    For example, we see that dht sends DHT_IATT_IN_XDATA_KEY in setxattr
    which will be unwound with the same key in the xdata-response which
    dht thinks is valid response and fills stbuf with invalid values
    leading to EIO
