In some situations where xhci removal happens parallel to xhci_handshake, we encounter a scenario where the xhci_handshake can't succeed, and it polls until timeout. If xhci_handshake runs until timeout it can on some platforms result in a long wait which might lead to a watchdog timeout. Add a helper that checks xhci status during the handshake, and exits if set state is entered. Use this helper in places where xhci_handshake is called unlocked and has a long timeout. For example xhci command timeout and xhci reset.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
