scsi: lpfc: Fix NULL pointer dereference during PCI error recovery Recent commit on patchset "lpfc updates for 11.2.0.14" fixed an issue about dereferencing a NULL pointer on port reset. The specific commit, named "lpfc: Fix system crash when port is reset.", is missing a check against NULL pointer on lpfc_els_flush_cmd() though. Since we destroy the queues on adapter resets, like in PCI error recovery path, we need the validation present on this patch in order to avoid a NULL pointer dereference when trying to flush commands of ELS wq, after it has been destroyed (which would lead to a kernel oops).
