Justin Tee 8a72289694 scsi: lpfc: Correct used_rpi count when devloss tmo fires with no recovery
[ Upstream commit db651ec22524eb8f9c854fbb4d9acd5d7e5be9e4 ]

A fabric controller can sometimes send an RDP request right before a link
down event.  Because of this outstanding RDP request, the driver does not
remove the last reference count on its ndlp causing a potential leak of RPI
resources when devloss tmo fires.

In lpfc_cmpl_els_rsp(), modify the NPIV clause to always allow the
lpfc_drop_node() routine to execute when not registered with SCSI
transport.

This relaxes the contraint that an NPIV ndlp must be in a specific state in
order to call lpfc_drop node.  Logic is revised such that the
lpfc_drop_node() routine is always called to ensure the last ndlp decrement
occurs.

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.
