[PATCH] scsi: initio: free SCB array on remove

[Guangshuo Li]

initio_probe_one() allocates an SCB array and stores it in host->scb.
The probe failure paths free this array, but the normal remove path
does not perform the corresponding cleanup.

As a result, the SCB array remains allocated after the driver is
removed and becomes unreachable once the SCSI host is released.

Free the SCB array in initio_remove_one(), matching the probe error
path.

This issue was found by manual code inspection.
