ASoC: wcd9335: Fix a memory leak in the error handling path of the probe function 

[ Upstream commit fc6fc81caa63900cef9ebb8b2e365c3ed5a9effb ]

If 'wcd9335_setup_irqs()' fails, me must release the memory allocated in
'wcd_clsh_ctrl_alloc()', as already done in the remove function.

Add an error handling path and the missing 'wcd_clsh_ctrl_free()' call.

Fixes: 20aedafdf4 ("ASoC: wcd9335: add support to wcd9335 codec")
