i2c: qcom-geni: Simplify error handling in probe function

Avoid repeating the error handling pattern:

        geni_se_resources_off(&gi2c->se);
        clk_disable_unprepare(gi2c->core_clk);
        return;

Introduce a single 'goto' exit label for cleanup in case of
errors. While there are currently two distinct exit points, there
is no overlap in their handling, allowing both branches to
coexist cleanly.
