Subject: [PATCH v1] drivers: edac: Drop unnecessary error check for debugfs_create_dir

This patch removes the error checking for debugfs_create_dir.
Even if we get an error from this function, other debugfs APIs will
handle the error value and doesn't crash in that case. Hence caller can
safely ignore the errors that occur during the creation of debugfs nodes.
