Tan Xiaojun 30f84a891b 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.
