dmaengine: lgm: Fix an error handling path in intel_ldma_probe()

ldma_clk_disable() calls both:
	clk_disable_unprepare(d->core_clk);
	reset_control_assert(d->rst);

So, should devm_reset_control_get_optional() fail, core_clk should not
be prepare_enable'd before it, otherwise it will never be
disable_unprepare'd.

Reorder the code to handle the error handling path as expected.

Fixes: 32d31c79 ("dmaengine: Add Intel LGM SoC DMA support.")
