[RFC PATCH 11/23] ASoC: pci/emu10k1: remove "set but not used' warnings

[Pierre-Louis Bossart]

Fix W=1 warnings. Mark variables used for reads as __always_unused.

sound/pci/emu10k1/emu10k1_main.c: In function
‘snd_emu10k1_cardbus_init’:
sound/pci/emu10k1/emu10k1_main.c:626:15: warning: variable ‘value’ set
but not used [-Wunused-but-set-variable]
  626 |  unsigned int value;
      |               ^~~~~
sound/pci/emu10k1/emu10k1_main.c: In function
‘snd_emu1010_load_firmware_entry’:
sound/pci/emu10k1/emu10k1_main.c:656:15: warning: variable
‘write_post’ set but not used [-Wunused-but-set-variable]
  656 |  unsigned int write_post;
      |               ^~~~~~~~~~
