Subject: scsi: qla2xxx: Remove WARN_ON_ONCE in qla2x00_status_cont_entry()
Patch-mainline: v5.4-rc4
Git-commit: 9bc6157f5fd0e898c94f3018d088a3419bde0d8f
References: bsc#1143706 bsc#1082635 bsc#1123034

Commit 88263208dd23 ("scsi: qla2xxx: Complain if sp->done() is not called
from the completion path") introduced the WARN_ON_ONCE in
qla2x00_status_cont_entry(). The assumption was that there is only one
status continuations element. According to the firmware documentation it is
possible that multiple status continuations are emitted by the firmware.

Fixes: 88263208dd23 ("scsi: qla2xxx: Complain if sp->done() is not called from the completion path")
