With faulty cables in PT2PT topology, an unintentional ndlp double kref decrement can occur. If a FLOGI request is outstanding before the link goes down, the missing FLOGI_ACC causes an F_Port ndlp to remain in the UNUSED state. During link down, lpfc_cleanup_rpis() is called and decrements an ndlp kref. Additionally, when the driver later decides to abort the FLOGI, the FLOGI completion handler decrements the ndlp kref a second time. Remove duplicate clean up logic in lpfc_cleanup_rpis() because the updated FLOGI completion handler already handles the ndlp kref decrement.

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.
