firewire: remove bogus check in fw_core_handle_request

This check is bogus:
  - Maximum asynchronous payload size for S800...S3200 is 4096.
  - The p->payload_length is totally uninteresting.  Only the
    request->length of the subsequently allocated and initialized
    struct fw_request is of significance.
