An hba-wide lock is taken in the nvme io completion routine. The lock covers null'ing of the nrport pointer in the cmd structure. The nrport member isn't necessary. After extracting the pointer from the command, the pointer was dereferenced to get the fc discovery node pointer. But the fc discovery node pointer is alrady in the command structure so the dereferrence was unnecessary. Eliminated the nrport structure member and its use, which also eliminates the port-wide lock.

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.
