[PATCH AUTOSEL 5.10 6/7] scsi: storvsc: Always set no_report_opcodes

[Sasha Levin]

From: Michael Kelley <mikelley@xxxxxxxxxxxxx>

[ Upstream commit 31d16e712bdcaee769de4780f72ff8d6cd3f0589 ]

Hyper-V synthetic SCSI devices do not support the MAINTENANCE_IN SCSI
command, so scsi_report_opcode() always fails, resulting in messages like
this:

hv_storvsc <guid>: tag#205 cmd 0xa3 status: scsi 0x2 srb 0x86 hv 0xc0000001

The recently added support for command duration limits calls
scsi_report_opcode() four times as each device comes online, which
significantly increases the number of messages logged in a system with many
disks.

Fix the problem by always marking Hyper-V synthetic SCSI devices as not
supporting scsi_report_opcode(). With this setting, the MAINTENANCE_IN SCSI
command is not issued and no messages are logged.
