scsi: core: sysfs: Correct sysfs attributes access rights
[ Upstream commit a2f54ff15c3bdc0132e20aae041607e2320dbd73 ]
The SCSI sysfs attributes "supported_mode" and "active_mode" do not
define a store method and thus cannot be modified. Correct the
DEVICE_ATTR() call for these two attributes to not include S_IWUSR to
allow write access as they are read-only.
