EDAC: Use edac_debugfs_remove_recursive()
debugfs_remove() is used to remove a file or a directory from the
debugfs filesystem, but mci->debugfs might not empty.
This can be triggered by the following sequence:
1) Enable CONFIG_EDAC_DEBUG
2) insmod an EDAC module (like i3000_edac or similar)
3) rmmod this module
4) we can see files remaining under <debugfs_mountpoint>/edac/ like
"fake_inject", for example.
Removing edac_core then, causes a NULL pointer dereference.
