usb: gadget: f_tcm: Send sense on cancelled transfer

If the transfer is cancelled due to a disconnect or driver tear down
(error code -ESHUTDOWN), then just free the command. However, if it got
cancelled due to other reasons, then send a sense CHECK CONDITION status
with TCM_CHECK_CONDITION_ABORT_CMD status to host notifying the delivery
failure. Note that this is separate from TASK MANAGEMENT function abort
task command, which will require a separate response IU.

See UAS-r04 section 8.
