scsi: hisi_sas: Check before using pointer variables

Browse source

[ Upstream commit 8dd10296be ]

In commit 4b329abc91 ("scsi: hisi_sas: Move slot variable definition in
hisi_sas_abort_task()"), we move the variables slot to the function head.
However, the variable slot may be NULL, we should check it in each branch.

Fixes: 4b329abc91 ("scsi: hisi_sas: Move slot variable definition in hisi_sas_abort_task()")
