The internal variable is just what xhci spec recommends as it says the output
context is not immediately
updated for example at endpoint doorbell ring. It's to make sure we don't read

on AMD platforms with SNPS 3.1 USB controller if stop endpoint command is
issued the controller does not respond, when the EP is not in running
state. HW completes the command execution and reports
"Context State Error" completion code. This is as per the spec. However
HW on receiving the second
