Fix W=1 warnings. Two variables are only used for debug logs, mark
with __maybe_unused:

sound/pci/korg1212/korg1212.c: In function ‘snd_korg1212_create’:
sound/pci/korg1212/korg1212.c:2152:36: warning: variable ‘iomem2_size’
set but not used [-Wunused-but-set-variable]
 2152 |  unsigned ioport_size, iomem_size, iomem2_size;
      |                                    ^~~~~~~~~~~
sound/pci/korg1212/korg1212.c:2152:11: warning: variable ‘ioport_size’
set but not used [-Wunused-but-set-variable]
 2152 |  unsigned ioport_size, iomem_size, iomem2_size;
      |           ^~~~~~~~~~~
