The axchg structure is a structure allocated early in the
lpfc_nvme_unsol_ls_handler() to represent the newly received exchange.
Upon error, the out_fail path in the routine unconditionally frees the
pointer, yet subsequently passes the pointer to the abort routine.
Additionally, the abort routine, lpfc_nvme_unsol_ls_issue_abort(), also
has a failure path that will attempt to delete the pointer on error.
Fix these errors by:
- Removing the unconditional free so that it stays valid if passed
to the abort routine.
- Revise the abort routine to not free the pointer. Instead, return
a success/failure status. Note: if success, the later completion of
the abort frees the structure.
- Back in the unsol_ls_handler() error path, if the abort routine was
skipped (thus no possible reference) or the abort routine returned
error, free the pointer.

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.
