Subject: [PATCH] ASoC: cs47l92: Simplify error handling code in 'cs47l92_probe()'

If 'madera_init_bus_error_irq()' fails,
'wm_adsp2_remove(&cs47l92->core.adsp[0])' will be called twice.
Once in the 'if' block, and once in the error handling path.
This is harmless, but one of this call can be axed.
