We currently have a special, separate, code path to acquire NIC access for the in-flight host-command workaround on 7000 series hardware. However, the normal code path here has grown a number of additional workarounds/semantics over time, such as reprobing the device if things fail. Rather than try to replicate any of this logic, call the normal grab_nic_access logic for the workaround. This changes the spinlock to _bh, but that's OK since it's just redundant, we already have soft-IRQs disabled when we get here, and so didn't (have to) do it again. Since it's only for commands there's however no point in making the code more complex just to not use _bh here.

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.
