Subject: scsi: qla2xxx: Fix a recently introduced kernel warning
Patch-mainline: v5.4-rc1
Git-commit: dd93b143706c636d3dfefe6cf355065d748b2473
References: bsc#1123034 bsc#1131304 bsc#1127988

According to the firmware documentation a status type 0 IOCB can be
followed by one or more status continuation type 0 IOCBs. Hence do not
complain if the completion function is not called from inside the status
type 0 IOCB handler.
