Subject: memory: tegra: Delete some dead code

Git-commit: 5a6b5d53833c92f05d9892e96d9034ff05df551d
Patch-mainline: v5.9-rc1
References: jsc#SLE-15847

The debugfs_create_dir() function never returns NULL and anyway the
correct behavior is to ignore errors in this situation.  The
debugfs_create_file() will become a no-op if "emc->debugfs.root" is an
error pointer.
