[PATCH] EDAC: use debugfs_remove_recursive instead of debugfs_remove

From: Tan Xiaojun
Date: Mon Oct 12 2015 - 22:16:58 EST


debugfs_remove is used to remove a file or an empty directory from
the debugfs filesystem, but mci->debugfs is not empty.

This is not easily discovered, because debugfs_remove return nothing
when failed.
