mtd: maps: add missing iounmap() in error path
This patch was triggered by the following Coccinelle error:
./drivers/mtd/maps/sc520cdp.c:246:3-9: \
ERROR: missing iounmap; ioremap on line 242 \
and execution via conditional on line 244
Since do_map_probe() is also invoked in this loop, it is also necessary to
map_destroy() any initialised struct mtd_info.
