[PATCH] zorro: Fix a resource leak in zorro7xx_remove_one()

[Christophe JAILLET]

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.

Fixes: 45804fbb00ee ("[SCSI] 53c700: Amiga Zorro NCR53c710 SCSI")
