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. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>
