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 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
