Some disks, such as the Seagate Cheetah 73LP FC with Sun firmware
(ST373405FSUN72G) respond to a START STOP UNIT command that spins down the
disk with a "Logical Unit Not Ready, Initialization Command Required".
Besides causing some dmesg spam, our sd(4) driver responds to such a response
by spinning the disk back up. Prevent this from happening by respecting
the SCSI_IGNORE_NOT_READY flag and using that flag when spinning down the
disk.
