hci_error_reset() return without calling hci_dev_do_open() when hci_dev_do_close() return error value which is not 0. Also, hci_dev_close() return hci_dev_do_close() function's return value. But, hci_dev_do_close() return always 0 even if hdev->shutdown return error value. So, fix hci_dev_do_close() to save and return the return value of the hdev->shutdown when it is called.

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.
