arm64: mm: Fix unused variable warning in zone_sizes_init
When building arm64 allnoconfig, CONFIG_ZONE_DMA and CONFIG_ZONE_DMA32
get disabled so there is a warning about max_dma being unused.
../arch/arm64/mm/init.c:215:16: warning: unused variable 'max_dma'
[-Wunused-variable]
unsigned long max_dma = min;
^
1 warning generated.
Add __maybe_unused to make this clear to the compiler.
Fixes: 1a8e1cef7603 ("arm64: use both ZONE_DMA and ZONE_DMA32")
