memory: tegra: Delete dead debugfs checking code
The debugfs_create_dir() function does not return NULL, it returns error pointers. But in normal situations like this where the caller is not dereferencing "emc->debugfs.root" then we are not supposed to check the return. So instead of fixing these checks, we should delete them.
