scsi: sim710: Fix resource leak by adding missing ioport_unmap() calls

The driver calls ioport_map() to map I/O ports in sim710_probe_common()
but never calls ioport_unmap() to release the mapping. This causes
resource leaks in both the error path when request_irq() fails and in
the normal device removal path via sim710_device_remove().

Add ioport_unmap() calls in the out_release error path and in
sim710_device_remove().
