[PATCH] scsi: qla2xxx: Remove WARN_ON_ONCE in qla2x00_status_cont_entry()
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.
