ebda_rsrc_controller() calls iounmap(io_mem) on the error path. It's
caller, ibmphp_access_ebda() also calls iounmap(io_mem) on good and
error paths. Removing the iounmap(io_mem) invocation inside
ebda_rsrc_controller().

Why am I fixing this?
I found this clean up item in drivers/pci/hotplug/TODO [lines 43-44]
and decided to fix it. This is my 2nd patch ever in linux so my
apologies for any style issues. I am very teachable. :)
