In a large SAN testing configuration, frequent target port toggle tests are occasionally resulting in missing lun path rediscoveries. An outstanding PRLI can be inflight when a target RSCN dissappearance occurs, causing the driver to retry PRLIs using invalid rpi contexts. Fix by verifying that an ndlp's state was not restarted from PRLI_ISSUE due to an intermediate RSCN. If not in a valid state, early exit PRLI completion handling. The last follow up RSCN indicating target reappearance retriggers PLOGI/PRLI with a valid rpi context and is expected to succeed in LUN path rediscovery.

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.
