ALSA: pci/es1938: remove 'set but not used' warning

Fix W=1 warning. Mark the 'audiostatus' variable as __always_unused.

sound/pci/es1938.c:1622:24: warning: variable ‘audiostatus’ set but
not used [-Wunused-but-set-variable]
 1622 |  unsigned char status, audiostatus;
      |                        ^~~~~~~~~~~
