[ALSA] sound: maestro3.c fix shadowed variable warnings

change id to elem_id as it is used to initialize each mixer element
sound/pci/maestro3.c:2071:25: warning: symbol 'id' shadows an earlier one
sound/pci/maestro3.c:67:13: originally declared here

index is used in each of these places to count over the dsp's memory,
change to the name dsp_index
sound/pci/maestro3.c:2572:9: warning: symbol 'index' shadows an earlier one
sound/pci/maestro3.c:66:12: originally declared here
sound/pci/maestro3.c:2604:9: warning: symbol 'index' shadows an earlier one
sound/pci/maestro3.c:66:12: originally declared here

[tiwai - fixed coding style issues as well]
