[xhci] Abort commands on timeout

When a command times out, abort it (via the Command Abort bit in the
Command Ring Control Register) so that subsequent commands may execute
as expected.

This improves robustness when a device fails to respond to the Set
Address command, since the subsequent Disable Slot command will now
succeed.
