scsi: zorro7xx: Fix a resource leak in zorro7xx_remove_one()

[ Upstream commit 16ed828b872d12ccba8f07bcc446ae89ba662f9c ]

The error handling path of the probe releases a resource that is not freed
in the remove function. In some cases, a ioremap() must be undone.

Add the missing iounmap() call in the remove function.
