common: globvar: let nvvar_remove() report non-existing variable
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.
