[2.6 patch] drivers/ieee1394/raw1394.c: fix a NULL pointer dereference

The coverity checker spotted that this was a NULL pointer dereference in 
the "if (copy_from_user(...))" case since the next step is to 
kfree(cache->filled_head).

There's no need to free cache at this point, and it's getting free'd 
later.
