James Smart 00292e0306 scsi: lpfc: Fix discovery failure when PLOGI is defered
When a target's link dropped, an RSCN was received to communicate the
change. The driver detected the loss of the target and issued and UNREG_RPI
mailbox command.  While that was being processed, another RSCN was received
to communicate the port coming back.  The driver deferred the PLOGI to the
port until the mailbox command finishes. When the mailbox command completed
it saw the pending port and called the routines to issue the
PLOGI. However, it forgot to clear the UNREG_INP state flag, so the PLOGI
xmt routine nooped the PLOGI request assuming it needed to wait for the
mailbox command.  At this point, login would never be re-attempted.

Clear UNREG_INP before issuing the deferred PLOGI.

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.
