James Smart 858f090696 scsi: lpfc: Fix rpi release when deleting vport
commit 97acd0019d5dadd9c0e111c2083c889bfe548f25 upstream.

A prior use-after-free mailbox fix solved it's problem by null'ing a ndlp
pointer.  However, further testing has shown that this change causes a
later state change to occasionally be skipped, which results in a reference
count never being decremented thus the rpi is never released, which causes
a vport delete to never succeed.

Revise the fix in the prior patch to no longer null the ndlp. Instead the
RELEASE_RPI flag is set which will drive the release of the rpi.

Given the new code was added at a deep indentation level, refactor the code
block using a new routine that avoids the indentation issues.

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.
