nvme: remove initialization of nvme_reqest::parent 



The parent field is in the cache line of nvme_request that is only
supposed to be accessed for split (child) I/Os.  All accesses to parent
are done from child-specific calls now, so it does not need to be
initialized in the common case of a non-split I/O.
nvme_request_add_child() will set parent when splitting occurs.
