usb: gadget: f_tcm: Decrement command ref count on cleanup
commit 3b2a52e88ab0c9469eaadd4d4c8f57d072477820 upstream.
We submitted the command with TARGET_SCF_ACK_KREF, which requires
acknowledgment of command completion. If the command fails, make sure to
decrement the ref count.
Fixes: cff834c16d23 ("usb-gadget/tcm: Convert to TARGET_SCF_ACK_KREF I/O krefs")
