nvme-fc: fix request private initialization
The patch made to avoid Coverity reporting of out of bounds access on aen_op moved the assignment of a pointer, leaving it null when it was subsequently used to calculate a private pointer. Thus the private pointer was bad. Move/correct the private pointer initialization to be in sync with the patch.
