ASoC: fsl: imx-rpmsg: use snd_soc_find_dai_with_mutex() in probe

Browse source 
imx_rpmsg_probe() calls snd_soc_find_dai() without holding client_mutex.
However, snd_soc_find_dai() has lockdep_assert_held(&client_mutex)
indicating callers must hold this lock, as the function iterates over the
global component list.

All other callers of snd_soc_find_dai() either hold client_mutex via the
snd_soc_bind_card() path or use the snd_soc_find_dai_with_mutex() wrapper.

Use snd_soc_find_dai_with_mutex() instead to fix the missing lock
protection.
