usb: chipidea: fix usage_count leak when autosuspend_delay is negative
The probe() calls pm_runtime_use_autosuspend(), but remove() does not call
pm_runtime_dont_use_autosuspend(). This can lead to a usage_count leak if
autosuspend_delay is set to a negative value.
The pm_runtime_use_autosuspend() also notes that it's important to undo
this with pm_runtime_dont_use_autosuspend() at driver exit time.

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 reStructuredText 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.
