A race condition between the context of devloss timeout handler and I/O completion caused devloss timeout handler de-referencing pointer that had been released. Added the check in lpfc_sli_validate_fcp_iocb() on LPFC_IO_ON_TXCMPLQ to capture the race condition of I/O completion and devloss timeout handler attemption for aborting the I/O. Also, added check on lpfc_cmd->rdata pointer before de-referenceing lpfc_cmd->rdata->pnode. Also, added protection in lpfc_sli_abort_iocb() routine on driver performed FCP I/O FLUSHING already under way before proceeding to aborting I/Os.

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.
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.
