ieee1394/csr1212: fix false positive kmemcheck report
kmemcheck reports a use of uninitialized memory here, but it's not
a real error. The structure in question has just been allocated, and
the whole field is initialized, but it happens in two steps.
We fix the false positive by inserting a kmemcheck annotation.
