[ALSA] Fix 'semaphore is not ready' problem with snd-intel8x0m

Browse Source 
Intel8x0-modem driver
With some intel based ac97 modems codec access semaphore is not cleared
after 0x54 AC97 register (GPIO_STATUS) reads. This may causes problems
with newly applied modem mixer (Off-hook switch) and in other cases.
