xhci: Fix Abort command event handling
This fixes issues with how we handle events generated by the xHCI
"command abort" command. first, depending on the state of the xHCI
controller, the COMMAND_ABORTED may not be generated. If the
controller was between commands, only the COMMAND_RING_STOPPED event
will be generated. Second, do not adjust the command ring "cur"
pointer as that just confuses the controller.
BUG=b:160354585,b:157123390
