[PATCH 4/6] common: globvar: let nvvar_remove() report non-existing variable

[Enrico Jorns]

The former implementation did not allow to detect whether the call to
nvvar_remove() succeeded or failed and always returned 0.

This changes the implementation to return 0 only if a variable with the
given name was found and return ENOENT otherwise.
