ASoC: samsung: i2s: Null pointer dereference on samsung_i2s_remove

Browse source

If (quirks & QUIRK_SEC_DAI == 0) then samsung_i2s_probe() doesn't allocate
sec_dai and pri_dai->sec_dai remains Null, but samsung_i2s_remove()
performs pri_dai->sec_dai dereference in any case.

The patch removes useless reinitialization of sec_dai at
samsung_i2s_remove(), because resources are under devm control.
