Orange Kao 029ac07bb9 EDAC/igen6: Avoid segmentation fault on module unload 
[ Upstream commit fefaae9039 ]

The segmentation fault happens because:

During modprobe:
1. In igen6_probe(), igen6_pvt will be allocated with kzalloc()
2. In igen6_register_mci(), mci->pvt_info will point to
   &igen6_pvt->imc[mc]

During rmmod:
1. In mci_release() in edac_mc.c, it will kfree(mci->pvt_info)
2. In igen6_remove(), it will kfree(igen6_pvt);

Fix this issue by setting mci->pvt_info to NULL to avoid the double
kfree.
