nvmet: remove a duplicate status assignment in nvmet_alloc_ctrl

In the function nvmet_alloc_ctrl() we assign status value before we
call nvmet_fine_get_subsys() to:

	status = NVME_SC_CONNECT_INVALID_PARAM | NVME_SC_DNR;

After we successfully find the subsystem we again set the status value
to:

	status = NVME_SC_CONNECT_INVALID_PARAM | NVME_SC_DNR;

Remove the duplicate status assignment value.
