Miaoqing Pan 08d80e4cd2 ath10k: fix fw crash by moving chip reset after napi disabled
On SMP platform, when continuously running wifi up/down, the napi
poll can be scheduled during chip reset, which will call
ath10k_pci_has_fw_crashed() to check the fw status. But in the reset
period, the value from FW_INDICATOR_ADDRESS register will return
0xdeadbeef, which also be treated as fw crash. Fix the issue by
moving chip reset after napi disabled.

README

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.
