network.py:ActionModule:run: does not honor _handle_src_option failures (#52745)

* network.py:ActionModule:run: does not honor _handle_src_option failures

PR #50301 moved template error handling out of run() and into its
own method in `_handle_src_option`; however, after the change run()
ignores the return value so any errors are ignored.

Reproduceable with `nxos_config/tests/common/src_invalid.yaml`

Verified fix with `nxos_config/tests/common/src_*` tests.

* nxos_config/tests/common/src_basic: Updated to test with src

This test was not actually testing with `src:` as it should have.

* Revert 412d7e change to plugins/action/network.py

PR #52912 fixed this already.

* nxos_config: fix src_invalid test
