James Smart 61184f1742 scsi: lpfc: Fix Oops in nvme_register with target logout/login
lpfc_nvme_register_port hit a null prev_ndlp pointer in a test with lots of
target ports swapping addresses. The oldport value was stale, thus it's
ndlp (prev_ndlp set to it) was used.

Fix by moving oldrport pointer checks, and if used prev_ndlp pointer
assignment, to be done while the lock is held.

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.
