[PATCH 1/2] EDAC: fix memleak in module init error path

[Johan Hovold]

Make sure to use put_device() to free the initialised struct device so
that resources managed by driver core also gets released in the event of
a registration failure.

Fixes: de3910eb79ac ("edac: change the mem allocation scheme to make 
Documentation/kobject.txt happy")
Fixes: 2d56b109e3a5 ("EDAC: Handle error path in edac_mc_sysfs_init() properly")
