ALSA: ice1712: Check correct return value to snd_i2c_sendbytes (EWS/DMX 6Fire)
Check for exact and correct return value to snd_i2c_sendbytes call for EWS/DMX 6Fire (snd_ice1712). Fixes a systemic error on every boot starting from kernel 5.1 onwards to snd_ice1712 driver ("cannot send pca") on Terratec EWS/DMX 6Fire PCI soundcards.
