nfp: fix the access to management firmware hanging

When running `ethtool -p` with the old management firmware,
the management firmware resource is not correctly released,
which causes firmware related malfunction: all the access
to management firmware hangs.

It releases the management firmware resource when set id
mode operation is not supported.

Fixes: ccb9bc1dfa44 ("nfp: add 'ethtool --identify' support")
