[SCSI] ipr: Enable logging of debug error data for all devices
The ipr driver has a sysfs attribute which can be used to adjust the logging level of the driver for error events. The error response data for commands can be dumped by increasing the logging level of the ipr driver. This currently only works for JBOD passthrough devices. This patch enables this function for all devices, including RAID devices, to aid in debugging problems.
