[PATCH] ASoC: davinci-mcasp: Fix an error handling path in 'davinci_mcasp_probe()'

[Christophe JAILLET]

All error handling paths in this function 'goto err' except this one.

If one of the 2 previous memory allocations fails, we should go through
the existing error handling path. Otherwise there is an unbalanced
pm_runtime_enable()/pm_runtime_disable().

Fixes: dd55ff8346a9 ("ASoC: davinci-mcasp: Add set_tdm_slots() support")
