0acb20a543 mt7601u: fix kernel crash unplugging the device
The following crash log can occur unplugging the usb dongle since,
after the urb poison in mt7601u_free_tx_queue(), usb_submit_urb() will
always fail resulting in a skb kfree while the skb has been already
queued.

Fix the issue enqueuing the skb only if usb_submit_urb() succeed.

Use the proper type for the queue ID variables to fix these warnings.
Additionally, rename the txq variable in mt7915_mcu_send_message to be
more neutral like mt7615_mcu_send_message.

f12758f6f9 mt76: mt7615: Fix fall-through warnings for Clang
In preparation to enable -Wimplicit-fallthrough for Clang, fix a
warning by replacing a /* fall through */ comment with the new
pseudo-keyword macro fallthrough; instead of letting the code fall
through to the next case.

Notice that Clang doesn't recognize /* fall through */ comments as
implicit fall-through markings.
