firmware: tegra: bpmp: Propagate debugfs errors

Browse Source 
The Tegra BPMP debugfs code returns -ENOMEM for most cases where calls
to debugfs_create_dir() or debugfs_create_file() fail. These debugfs
functions return an ERR_PTR with the actual error code on failure.
Therefore, update the Tegra BPMP debugfs code to propagate the actual
error code on failure.
