[PATCH AUTOSEL 5.13 047/114] scsi: qedi: Fix null ref during abort handling

[Sasha Levin]

From: Mike Christie <michael.christie@xxxxxxxxxx>

[ Upstream commit 5777b7f0f03ce49372203b6521631f62f2810c8f ]

If qedi_process_cmd_cleanup_resp finds the cmd it frees the work and sets
list_tmf_work to NULL, so qedi_tmf_work should check if list_tmf_work is
non-NULL when it wants to force cleanup.
