scsi: sd: Keep disk read-only when re-reading partition
If the read-only flag is true on a SCSI disk, re-reading the partition table sets the flag back to false. To observe this bug, you can run: 1. blockdev --setro /dev/sda 2. blockdev --rereadpt /dev/sda 3. blockdev --getro /dev/sda This commit reads the disk's old state and combines it with the device disk-reported state rather than unconditionally marking it as RW.
