ALSA: hda: fix unused variable warning
When CONFIG_X86=n function azx_snoop doesn't use the variable chip it
only returns true.
sound/pci/hda/hda_intel.c: In function ‘dma_alloc_pages’:
sound/pci/hda/hda_intel.c:2002:14: warning: unused variable ‘chip’ [-Wunused-variable]
struct azx *chip = bus_to_azx(bus);
^~~~
Create a inline function of azx_snoop.
Fixes: a41d122449be ("ALSA: hda - Embed bus into controller object")
