lib: fix setting temporary log options for libyang

By calling `ly_log_options` with `LY_LOSTORE`, the current code
effectively disables libyang logging and never enables it back. The call
is done to get the current logging options, but we don't really need
that. When looking for a schema node, we don't want neither to log nor
to store the error, so simply set the temporary options to 0.
