[SCSI] ipr: Disk remove path cleanup
Instead of NULLing the resource entry pointer when a disk goes away to prevent any new commands being sent to it, set the adapter resource handle to an invalid value so new ops getting sent to it will fail with a selection timeout response. This patch is needed for future SATA patches. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
