code_relocation: fix ruff SIM102 warning

The ruff python linter produces a SIM102 warning when there are nested if
statements which can be collapsed into a single if statement:

    if foo:
        if bar:
	    ...

...becomes...

    if foo and bar:
        ...

This patch corrects the single instance of this issue in the script.
