[PATCH] drivers/edac/i3200_edac.c: add missing iounmap

[Julia Lawall]

From: Julia Lawall <Julia.Lawall@xxxxxxx>

Add iounmap in the case where window has already been allocated.
Reorganize the error handling code at the end of the function so that if is
not needed.

Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx>
