Subject: ib_srp: Remove WARN_ON in srp_terminate_io()
Patch-mainline: v4.20-rc1
Git-commit: 56e027a604c80b1106786f8426e7cc5dbacb53b2
References: bsc#1103992 FATE#326009

The WARN_ON() is pointless as the rport is placed in SDEV_TRANSPORT_OFFLINE
at that time, so no new commands can be submitted via srp_queuecommand()
