James Smart 4550f9c75e scsi: lpfc: Fix crash in lpfc_sli_ringtxcmpl_put when nvmet gets an abort request.
When running nvme detach-ns /dev/nvme0n1 -n 1 command, the nvmet lpfc
driver crashes with this stack dump:

kernel BUG at /root/NVME/lpfc_8.4/lpfc_sli.c:1393!
invalid opcode: 0000 [#1] SMP
Workqueue: nvmet-fc-cpu0 nvmet_fc_do_work_on_cpu [nvmet_fc]

Crash is due to an uninitialized iocbq->vport pointer.

Explicitly set the iocbq->vport field to phba->pport in
lpfc_nvmet_sol_fcp_issue_abort as it does all abort iocbq initialization
in the routine.  Using phba->pport is ok because target does not support
NPIV instances.

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
