xhci: Move allocating of command for new_dequeue_state to queue_set_tr_deq()
There are multiple reasons for this:
1) This fixes a missing check for xhci_alloc_command failing in
xhci_handle_cmd_stop_ep()
2) This adds a warning when we cannot set the new dequeue state because of
xhci_alloc_command failing
3) It puts the allocation of the command after the sanity checks in
queue_set_tr_deq(), avoiding leaking the command if those fail
4) Since queue_set_tr_deq now owns the command it can free it if queue_command
fails
5) It reduces code duplication
